From Olivier Benghozi via https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7734
BGP bad decoding for Graceful Restart Capability with only helper support
BGP Capability in OPEN message: Graceful restart capability (64).
So when the length of the capability value is smaller that 6 (6 meaning full
support of GR capa, with significants elements and at least one AFI/SAFI), the
code interprets it as erroneous.
However,as described in RFC4724: " When a sender of this capability does not
include any <AFI, SAFI> in the capability, it means that the sender is not
capable of preserving its forwarding state during BGP restart, but supports
procedures for the Receiving Speaker (as defined in Section 4.2 of this
document). In that case, the value of the Restart Time field advertised by the
sender is irrelevant".
So, length of exactly 2 is valid but has to be interpreted with a particular
meaning.
In the dissector code, a length of 2 should be a special case for this capa,
decoding as "Graceful Restart helper mode only" or something like that, and
maybe also displaying an expert message if the Restart flag is not 0 in this
case, since here it's not expected to be possible.

Move show_exception() and show_reported_bounds_error() to
epan/show_exception.c, as it's used outside
epan/dissectors/packet-frame.c. Update their callers to include
<epan/show_exception.h> to get their declaration.
Add a CATCH_NONFATAL_ERRORS macro that catches all exceptions that, if
there's more stuff in the packet to dissect after the dissector call
that threw the exception, doesn't mean you shouldn't go ahead and
dissect that stuff. Use it in all those cases, including ones where
BoundsError was inappropriately being caught (you want those passed up
to the top level, so that the packet is reported as having been cut
short in the capture process).
Add a CATCH_BOUNDS_ERRORS macro that catches all exceptions that
correspond to running past the end of the data for a tvbuff; use it
rather than explicitly catching those exceptions individually, and
rather than just catching all exceptions (the only place that
DissectorError should be caught, for example, is at the top level, so
dissector bugs show up in the protocol tree).
Don't catch and then immediately rethrow exceptions without doing
anything else; just let the exceptions go up to the final catcher.
Use show_exception() to report non-fatal errors, rather than doing it
yourself.
If a dissector is called from Lua, catch all non-fatal errors and use
show_exception() to report them rather than catching only
ReportedBoundsError and adding a proto_malformed item.
Don't catch exceptions when constructing a trailer tvbuff in
packet-ieee8023.c - just construct it after the payload has been
dissected, and let whatever exceptions that throws be handled at the top
level.
Avoid some TRY/CATCH/ENDTRY cases by using checks such as
tvb_bytes_exist() before even looking in the tvbuff.

BGP: Remove redundant text in Path Attributes.
Also added display of lower-order four bits of the Attribute Flags ("unused").
Current implementation of displaying path attribute flags shows flag description twice if the flag was set.
For example, with Optional and Length set, the attribute flags were displayed as follows:
Flags: 0x90, Optional, Length: Optional, Non-transitive, Complete, Extended Length
1... .... = Optional: Optional
.0.. .... = Transitive: Non-transitive
..0. .... = Partial: Complete
...1 .... = Length: Extended length
Now they are displayed as follows:
Flags: 0x90, Optional, Extended-Length, Non-transitive, Complete
1... .... = Optional: Set
.0.. .... = Transitive: Not set
..0. .... = Partial: Not set
...1 .... = Extended-Length: Set
.... 0000 = Unused: 0x0

BGP: Remove redundant text in Path Attributes.
Also added display of lower-order four bits of the Attribute Flags ("unused").
Current implementation of displaying path attribute flags shows flag description twice if the flag was set.
For example, with Optional and Length set, the attribute flags were displayed as follows:
Flags: 0x90, Optional, Length: Optional, Non-transitive, Complete, Extended Length
1... .... = Optional: Optional
.0.. .... = Transitive: Non-transitive
..0. .... = Partial: Complete
...1 .... = Length: Extended length
Now they are displayed as follows:
Flags: 0x90, Optional, Extended-Length, Non-transitive, Complete
1... .... = Optional: Set
.0.. .... = Transitive: Not set
..0. .... = Partial: Not set
...1 .... = Extended-Length: Set
.... 0000 = Unused: 0x0

/* BGP Multiprotocol Next Hop Principles
*
* BGP Multiprotocol support is specified over a large variety of
* RFCs for different < AFI , SAFI > pairs , which leaves some theoretical
* pairings undefined ( e . g . , the Abstract of RFC 4760 contemplates
* supporting the IPX address family ) as well as leading to some
* omissions , contradictions , and inconsistencies . However , some general
* principles that apply across ( nearly ) all extant pairs exist .
*
* 1. Global IPv6 addresses can be followed by a link - local IPv6 address
*
* RFC 2545 specifies in section 3 , " Constructing the Next Hop field, "
* that when the next hop address type is IPv6 , the address given should
* be in global ( or site - local ) unicast address scope , and it shall be
* followed by the link - local address if and only if the BGP speaker shares
* a common subnet with the address and the peer the route is being
* advertised to .
*
* The wording implies that this holds for any < AFI , SAFI > pair where
* a IPv6 address is used , and RFCs 5549 , 7752 , and 8950 demonstrate that
* this explicitly holds for the most common ones , including for VPN - IPv6
* addresses ( where the route distinguisher field also appears , see
* RFC 4659 ) . Sometimes the possibility is elided where it is known to
* exist e . g . RFC 7606 7.11 MP_REACH_NLRI " For example, if RFC5549 is in
* use , then the next hop would have to have a length of 4 or 16. " Thus
* it is possible that its omission in other RFCs covering new < AFI , SAFI >
* pairs is an oversight .
*
* 2. [ VPN - ] IPv4 NLRI can have [ VPN - ] IPv6 Next Hop addresses
*
* RFCs 5549 and 8950 declare that the next hop address may not necessarily
* belong to the address family specified by the AFI , updating RFC 2858 ,
* specifically addressing the case of IPv6 islands across a IPv4 core
* and vice versa .
*
* IPv4 addresses can easily be mapped into IPv6 addresses , and that
* is the solution for one case , but in the other the Next Hop must be an
* IPv6 ( or VPN - IPv6 ) address even though the NLRI is IPv4 .
*
* The wording of RFC 8950 strongly implies that the intent is to allow
* IPv6 Net Hop addresses for any case of IPv4 or VPN - IPv4 NLRI , providing
* a BGP Capability to declare that the BGP speakers supports a different
* Next Hop AFI for < AFI , SAFI > pairs defined without this capability ,
* and noting those ( like < 1 , 132 > , SAFNUM_ROUTE_TARGET , RFC 4684 ) that
* consider the possibility from the start .
*
* 3. Next Hop Route Distinguisher ( RD ) is 0 or omitted
*
* RDs do not have a meaning in the Next Hop network address . However , when
* RFC 2547 introduced the VPN - IPv4 address family , at that point the Next
* Hop address family had to be the same as the NLRI address family , so the
* RD was set to all 0. Later defined < AFI , SAFI > pairs with RDs in their
* NLRI have either used this custom of a 0 RD , or else omitted it and
* only had the IP address in the Next Hop .

From Olivier Benghozi via https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7734
BGP bad decoding for Graceful Restart Capability with only helper support
BGP Capability in OPEN message: Graceful restart capability (64).
So when the length of the capability value is smaller that 6 (6 meaning full
support of GR capa, with significants elements and at least one AFI/SAFI), the
code interprets it as erroneous.
However,as described in RFC4724: " When a sender of this capability does not
include any <AFI, SAFI> in the capability, it means that the sender is not
capable of preserving its forwarding state during BGP restart, but supports
procedures for the Receiving Speaker (as defined in Section 4.2 of this
document). In that case, the value of the Restart Time field advertised by the
sender is irrelevant".
So, length of exactly 2 is valid but has to be interpreted with a particular
meaning.
In the dissector code, a length of 2 should be a special case for this capa,
decoding as "Graceful Restart helper mode only" or something like that, and
maybe also displaying an expert message if the Restart flag is not 0 in this
case, since here it's not expected to be possible.

BGP: Validate length of Path Attribute records.
Bug 13741 showed a case where the BGP dissector's failure to validate the
length of the Path Attribute record allowed a pathological BGP UPDATE packet to
generate more than one million items in the protocol tree by repeatedly
dissecting certain segments of the packet.
It's easy enough to detect when the Path Attribute length cannot be valid, so
let's do so. When the condition arises, let's raise an Expert Info error in
the same style and format as used elsewhere in the same routine, and abandon
dissection of the Path Attributes list.
With this check in place, an incorrect length computation is revealed at a
callsite. This would only have prevented a small (less than 5 bytes) Path
Attribute from being dissected if it was at the very end of the Path Attributes
list, but the bounds checking added in this change makes this problem much more
apparent, so we fix the length computation while we're here.
Testing Done: Built wireshark on Linux amd64. Using bgp.pcap from the Sample
Captures page on the wiki, verified that the dissection of the UPDATE
packets were unaltered by this fix. Using the capture attached to bug 13741
(clusterfuzz-testcase-minimized-6689222578667520.pcap), verified that the
packet no longer triggers the "too many items" exception, instead we see
an Expert Info for each oversized Path Attribute length, and eventually an
exception for "length of contained item exceeds length of containing item".
30,000 iterations of fuzz test with bgp.pcap as input, and many iterations
of randpkt-test too. Crafted a packet with a 3-byte ATOMIC_AGGREGATE Path
Attribute at the end of the Path Attributes list; Before this change, an
exception is raised during dissection, but after this change it is dissected
correctly.

BGP: Validate length of Path Attribute records.
Bug 13741 showed a case where the BGP dissector's failure to validate the
length of the Path Attribute record allowed a pathological BGP UPDATE packet to
generate more than one million items in the protocol tree by repeatedly
dissecting certain segments of the packet.
It's easy enough to detect when the Path Attribute length cannot be valid, so
let's do so. When the condition arises, let's raise an Expert Info error in
the same style and format as used elsewhere in the same routine, and abandon
dissection of the Path Attributes list.
With this check in place, an incorrect length computation is revealed at a
callsite. This would only have prevented a small (less than 5 bytes) Path
Attribute from being dissected if it was at the very end of the Path Attributes
list, but the bounds checking added in this change makes this problem much more
apparent, so we fix the length computation while we're here.
Testing Done: Built wireshark on Linux amd64. Using bgp.pcap from the Sample
Captures page on the wiki, verified that the dissection of the UPDATE
packets were unaltered by this fix. Using the capture attached to bug 13741
(clusterfuzz-testcase-minimized-6689222578667520.pcap), verified that the
packet no longer triggers the "too many items" exception, instead we see
an Expert Info for each oversized Path Attribute length, and eventually an
exception for "length of contained item exceeds length of containing item".
30,000 iterations of fuzz test with bgp.pcap as input, and many iterations
of randpkt-test too. Crafted a packet with a 3-byte ATOMIC_AGGREGATE Path
Attribute at the end of the Path Attributes list; Before this change, an
exception is raised during dissection, but after this change it is dissected
correctly.

that threw the exception, doesn't mean you shouldn't go ahead and
dissect that stuff. Use it in all those cases, including ones where
BoundsError was inappropriately being caught (you want those passed up
to the top level, so that the packet is reported as having been cut
short in the capture process).
Add a CATCH_BOUNDS_ERRORS macro that catches all exceptions that
correspond to running past the end of the data for a tvbuff; use it
rather than explicitly catching those exceptions individually, and
rather than just catching all exceptions (the only place that
DissectorError should be caught, for example, is at the top level, so
dissector bugs show up in the protocol tree).
Don't catch and then immediately rethrow exceptions without doing
anything else; just let the exceptions go up to the final catcher.
Use show_exception() to report non-fatal errors, rather than doing it
yourself.
If a dissector is called from Lua, catch all non-fatal errors and use
show_exception() to report them rather than catching only
ReportedBoundsError and adding a proto_malformed item.
Don't catch exceptions when constructing a trailer tvbuff in
packet-ieee8023.c - just construct it after the payload has been
dissected, and let whatever exceptions that throws be handled at the top
level.
Avoid some TRY/CATCH/ENDTRY cases by using checks such as

show_exception() to report them rather than catching only
ReportedBoundsError and adding a proto_malformed item.
Don't catch exceptions when constructing a trailer tvbuff in
packet-ieee8023.c - just construct it after the payload has been
dissected, and let whatever exceptions that throws be handled at the top
level.
Avoid some TRY/CATCH/ENDTRY cases by using checks such as
tvb_bytes_exist() before even looking in the tvbuff.

BGP: Remove redundant text in Path Attributes.
Also added display of lower-order four bits of the Attribute Flags ("unused").
Current implementation of displaying path attribute flags shows flag description twice if the flag was set.
For example, with Optional and Length set, the attribute flags were displayed as follows:
Flags: 0x90, Optional, Length: Optional, Non-transitive, Complete, Extended Length
1... .... = Optional: Optional
.0.. .... = Transitive: Non-transitive
..0. .... = Partial: Complete
...1 .... = Length: Extended length
Now they are displayed as follows:

1... .... = Optional: Set
.0.. .... = Transitive: Not set
..0. .... = Partial: Not set
...1 .... = Extended-Length: Set
