The build-netlab job was side-effecting the test-* jobs,
and if for some reason Gitlab scheduled build-netlab before
other pipeline's test-* jobs finished, these jobs got a wrong
binary, possibly failing. Solved by using explicit artifacts, which is
not the fastest way to do this (we could keep the binaries named there)
but it's the gitlab-right way to do this.
Several users build BIRD with excluded support for protocols they don't
need. Testing single-protocol builds; the assumption is that if single
protocols and all protocols are buildable, then possibly any reasonable
combination is buildable as well.
Minor change by committer.
The commit 21213be523 expanded private_id
in route source to u64, but forgot to modify function arguments, so it
was still cropped at 32-bit, which may cause some collisions for L3VPN.
This patch fixes that.
On BSD, the onlink flag is not tracked or reported by kernel. We are
using an heuristic that assigns the onlink flag to routes scanned from
the kernel. We should use the same heuristic even in BSD-Netlink
case, as the onlink flag is not reported here too.
Thanks to Björn König for the original patch.
The Babel seqno wraps around when reaching its maximum value (UINT16_MAX).
When comparing seqnos, this has to be taken into account. Therefore,
plain number comparisons do not work.
Implement several options (min/max graceful restart time, min/max long
lived stale time) to override graceful restart and long-lived graceful
restart timer values, as suggested by RFC 9494.
It seems that it should be 'providers' instead of 'provider'.
It matches keyword declaration and documentation. Mismatch beween keyword
declaration also breaks static-only builds.
Fix several errors including:
- Unaligned memory access to 'Length of Error Text' field
- No validation of 'Length of Encapsulated PDU' field
- No validation of 'Error Code' field
- No validation of characters in diagnostic message
All the 'dump something' CLI commands now have a new mandatory
argument -- name of the file where to dump the data. This allows
for more flexible dumping even for production deployments where
the debug output is by default off.
Also the dump commands are now restricted (they weren't before)
to assure that only the appropriate users can run these time consuming
commands.
When printing near the end of the buffer, there was an overflow in two cases:
(1) %c and size is zero
(2) %1N, %1I, %1I4, %1I6 (auto-fill field_width for Net or IP), size is
more than actual length of the net/ip but less than the auto-filled
field width.
Manual code examination showed that nothing could have ever triggered
this behavior. All older versions of BIRD, including BIRD 3 development
versions, are totally safe. This exact overflow has been found while
implementing a new feature in later commits.
Instead of several levels of functions, just have two functions
(one for routes, the other for end-of-rib), this allows to create
messages in a simple linear fashion.
Also reduce three duplicite functions to construct BGP header for
BMP messages to just one.
This commit is quite a substantial rework of the underlying layers in
BMP TX:
- several unnecessary layers of indirection dropped, including most of
the original BMP's buffer machinery
- all messages are now written directly into one protocol's buffer
allocated for the whole time big enough to fit every possible message
- output blocks are allocated by pages and immediately returned when
used, improving the overall memory footprint
- no intermediary allocation is done from the heap altogether
- there is a documented and configurable limit on the TX queue size
We shouldn't convert bytes 2 and 3 of the PDU blindly, there are several
cases where these are used by bytes. Instead, the conversion is done
only where needed.
This fixes misinterpretation bug of ASPA PDU flags on little endian
architectures.
The strcmp function is not guaranteed to return -1 or +1
but any negative or positive value if the input strings
are different. Fixed the false assumption which triggered
a build bug on emulated arm64.
The patch initializes logging in unit tests. Previously, unit tests did
not initialize logging and other subsystems, just resources. But
resource_init() could under certain circumstances trigger logging and
cause crash.
The bug was Found by Jakub Ruzicka, dissected by David Petera and Maria
Matejka, disguised as failing build for Debian arm64 in pbuilder
emulation which did not like disabling THP.
Fixes#42.
The END_OF_DATA PDU was extended in version 1, so it has different length
in different versions. We should do the PDU length check according to its
version.
Adds ability to override time format of show commands for current CLI session
so that it does not depend on configuration and may ease parsing when CLI is
called from tools.
Minor changes by committer.
The original algorithm assumed principles not consistent with the RFC
and could have lead to false invalids.
Also added filter tests showing also how the ASPA literals are used in
the static protocol.
