* Increase YPMAXRECORD to 16M to be compatible with Linux.Konstantin Belousov2019-08-123-3/+3
| | | | | | | | | | | | | | | | | | | | | | | Since YP protocol definition uses the constant to declare variable-size opaque byte strings, the change should be binary compatible with existing installations which do not expose keys or values larger than 1024 bytes. All uses of local variables with YPMAXRECORD sizes were removed to avoid insane stack use. On the other hand, variables with static lifetime should be fine and only result in increased VA use. Glibc made same change, increasing the allowed length for keys and values in YP to 16M, in 2013.

* Reduce NL_ARGMAX to 4096 to match Linux.Brooks Davis2018-10-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | NL_ARGMAX is the maximum number of positional arguments supported by printf(3). Prior to r308145 it was declared as 99 and not enforced. r308145 added enforcement and increased the value to 64k. Unfortunately, development versions of PostgreSQL used the system definition to allocate and zero an NL_ARGMAX * 4 sized array on the stack of its snprintf implementation with measurable performance impacts. This has been fixed in new PostgreSQL versions, but it is possible that other programs suffer from this problem. A value of 4096 puts us on par with Linux and is certainly large enough for any reasonable program.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | summits at BSDCan and BSDCam in 2017. The TCP Blackbox Recorder allows you to capture events on a TCP connection in a ring buffer. It stores metadata with the event. It optionally stores the TCP header associated with an event (if the event is associated with a packet) and also optionally stores information on the sockets. It supports setting a log ID on a TCP connection and using this to correlate multiple connections that share a common log ID. You can log connections in different modes. If you are doing a coordinated test with a particular connection, you may tell the system to put it in mode 4 (continuous dump). Or, if you just want to monitor for errors, you can put it in mode 1 (ring buffer) and dump all the ring buffers associated with the connection ID when we receive an error signal for that connection ID. You can set a default mode that will be applied to a particular ratio of incoming connections. You can also manually set a mode using a socket option. This commit includes only basic probes. rrs@ has added quite an abundance of probes in his TCP development work. He plans to commit those soon. There are user-space programs which we plan to commit as ports. These read the data from the log device and output pcapng files, and then let you analyze the data (and metadata) in the pcapng files.

Tests for both system calls are provided. Coverage is believed to be at least as comprehensive as LTP getrandom(2) test coverage.

The utility allows to store the dump in format <address> <value> into a file, to reset the dump content, and to manually initiate the dump. A call to mlx5_fwdump() should be added at the places where a dump must be fetched automatically. The most likely place is right before a firmware reset request.

For example dhclient(8) which is sandboxed is unable to open /dev/null to close stdio instead it's allows to fail daemon(3) function to close the descriptors and then do it explicit in code. Instead of such hacks we can use now daemonfd. This API can be also helpful to migrate system to platforms like CheriBSD.

* Remove basename_r(3).Ed Schouten2017-12-081-1/+0
| | | | | | | | | | | | | | | | | | Now that the POSIX working group is going to require that basename(3) and dirname(3) are thread-safe in future revisions of the standard, there is even less of a need to provide basename_r(3). Remove this function to prevent people from writing code that only builds on FreeBSD and Bionic. Removing this function seems to break exactly one port: sbruno@'s qemu-user-static. I will send him a pull request on GitHub in a bit. __FreeBSD_version will not be bumped, as any value from 2017 can be used to test for the presence of a thread-safe basename(3)/dirname(3).
