The ofp_stats struct length field includes the fixed 4 bytes.
If the length is smaller than that, report the length error
and break out. In particular, a value of zero can cause
infinite loops if this isn't done.
There's no point in trying to decompress a message with
length zero, and some of the third party decompression
libraries (e.g. zstd) can give unexpected results that
lead to infinite loops if we do so. A message length zero
is almost surely a file with errors.
Currently the autocompletion engine always suggests a protocol
field completion, even in places where it isn't syntactically
valid.
Fix that by compiling the preamble to the token under the cursor
and checking the returned error. If it is DF_ERROR_UNEXPECTED_END
that indicates a field or literal value was expected. Otherwise
a field replacement is not valid in this position.
Fixes#12811.
Store pointer to first gap to reduce number of full list traversals
needed when linking new fragments. When all captured fragments are in
order, the first gap is effectively pointing to list tail. The best case
scenario, where the list traversals are completely eliminated, happens
every time for protocols that always have the fragments ordered (most
notably USBLL Full-Speed capture containing Bulk OUT transfers with
a lot of retransmissions).
The memory usage is increased by a single pointer and 32-bit contiguous
length counter per fragment head. The additional CPU usage is constant
per insertion, i.e. does not increase with the number of fragments in
the list.
Fixes#17311
display_extension_block is supposed to return the current offset,
not the number of bytes remaining, which can be less than the current
offset and cause an infinite loop. In the case of errors, set
lastheader and return the current offset to break out of loops.
Adds missing NULL-termination in headerfield list in
dissect_dect_mitel_eth_mac_con_ind and removes handover to general data
dissector as this is path is no longer reached due to handling the
different message types within this dissector.
Only dissectors are using this function and there is no use case,
as far as I know, that requires its use. Any limitation of length
is imposed transparently by the UI backend.
This function is problematic because it is not Unicode aware and
will truncate a string on an arbitrary byte boundary for multibyte
strings.
Replace its use with a normal strbuf without a length limite and
remove the function because it is not useful and the ITEM_LABEL_LENGTH
parameter does not belong in wmem anyway.
CitrixAGBasic Authentication has Base64 encoded values. The result of
Base64 decoding is not guaranteed to be valid UTF-8 (or ASCII), so
verify it.
Also add the username and password to the credentials tap.
Fix#18677.
The dynamic hf entries for HTTP2 read from the UAT should be
changed when the UAT is changed or reset, not on each file
load and file close. If a field is added as a column, coloring
rule, or filter, and the capture file is changed, deregistering
the field and reregistering it can cause a crash.
Use the same approach as with HTTP and SIP, slightly modified
because in HTTP2 the header fields hash contains the static
headers as well, to prevent adding duplicate entries via the UAT.
Fix#14768
When CIMD indicates that a message was sent in the 7 bit GSM alphabet,
each character has been converted to ASCII or ISO-8559-1 with the
use of combining escape sequences for characters not present in
the destination encoding. Properly convert back to GSM 7 bit encoding
and then to UTF-8 for display.
Fix#18676.
https://cmake.org/cmake/help/latest/release/3.25.html says:
"On Windows, when targeting the MSVC ABI, the find_library() command now
accepts .a file names after first considering .lib. This is symmetric
with existing behavior when targeting the GNU ABI, in which the command
accepts .lib file names after first considering .a."
If "MSVC" is defined, only search for libsmi-2. This keeps us from finding
libsmi.a. Set NO_SYSTEM_ENVIRONMENT_PATH when we're searching for zlib. This
keeps us from finding Strawberry Perl's version.
Some SpanDSP builds link with LibTIFF, but our Windows version doesn't.
Return an struct containing error information. This simplifies
the interface to more easily provide richer diagnostics in the future.
Add an error code besides a human-readable error string to allow
checking programmatically for errors in a robust manner. Currently
there is only a generic error code, it is expected to increase
in the future.
Move error location information to the struct. Change callers and
implementation to use the new interface.
Adds dissection of the SYNC message type with the following payloads:
* FREQ_CTRL_MODE_IND
* FREQ_CTRL_MODE_CFM
* SET_FREQUENCY
* START_MAC_SLAVE_MODE_IND
* SYSTEM_SEARCH_IND
* SYSTEM_SEARCH_CFM
* PHASE_OFS_WITH_RSSI_IND
The dissection of the DECT-MITEL-RFP protocol is based upon findings
that resulted in rfpproxy, so I think it is a good idea to also name the
author in the source file
