* Remove MK_GSSAPILexi Winter17 hours1-3/+3
| | | | | | | | | | | | | | | For MIT Kerberos, MK_GSSAPI has no meaning: GSSAPI is a required part of Kerberos and is always built if MK_KERBEROS is enabled. Backport this behaviour to Heimdal so it works the same way. While here, change Heimdal's libcom_err and compile_et to be selected by MK_KERBEROS, not MK_KERBEROS_SUPPORT, since these are part of Kerberos and third-party users might need it even if Kerberos support is disabled in the base system. This means MK_KERBEROS_SUPPORT installs the same files with both MIT and Heimdal. Reviewed by: cy Differential Revision: https://reviews.freebsd.org/D51859

| | | | | | | | | | | | | | | The 'nadd' returned by these calls is the number of addresses actually added or deleted. It can differ from the number userspace sent to the kernel if the addresses are already present (or not present for the delete case). This meant that if all of the addresses were already handled the kernel would return zero, putting us in an infinite loop. Handle this, and extend the test case to provoke this scenario.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This brings in a merge from jemalloc 5.3.0. It's almost fully scripted, except: Three conflicts resolved by hand: include/jemalloc/internal/test_hooks.h Use the new name src/extent.c Use the new code src/jemalloc.c Use the new code since je_realloc has moved The script is recorded in FREEBSD-upgrade. The old script did svn commands that were basically a rebase of our changes. This update has a series of diff reduction changes before this. Note: I'd planned on fixing the above three conflicts with commits, but ran out of time when I did this work in January. I got discouraged when jemalloc was EOL'd and didn't pick this back up. I did the above by hand to get this into FreeBSD 15.0 This work is a repeat of the work by Minsoo Choo who did all these changes and created a pull request. Given the importance of jemalloc, I audited these changes by redoing them in this series of commits (and with the script that was checked in). I did this to confince myself and anybody else in doubt that there was no supply chain attack. The diffs between this series of commits and Minsoo's work are minor (though the version skew makes adds some noise). Interested parties can independent audit each step, I hope. I've listed Minsoo as a co-author since without his pull request to test again, this wouldn't have been possible. Thanks to brooks@ for help with getting the jemalloc 3 ABI compat symbols right.

| | | | | | | | | | | | | | | | As pointed out in the PR and the article linked below, the switch to insertion sort in the BSD qsort code is based on a misunderstanding of Knuth's TAOCP and is actually a pessimization.

* kern: fix setgroups(2) and getgroups(2) to match other platformsKyle Evans6 days4-27/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | On most other platforms observed, including OpenBSD, NetBSD, and Linux, these system calls have long since been converted to only touching the supplementary groups of the process. This poses both portability and security concerns in porting software to and from FreeBSD, as this subtle difference is a landmine waiting to happen. Bugs have been discovered even in FreeBSD-local sources, since this behavior is somewhat unintuitive (see, e.g., fix 48fd05999b0f for chroot(8)). Now that the egid is tracked outside of cr_groups in our ucred, convert the syscalls to deal with only supplementary groups. Some remaining stragglers in base that had baked in assumptions about these syscalls are fixed in the process to avoid heartburn in conversion. For relnotes: application developers should audit their use of both setgroups(2) and getgroups(2) for signs that they had assumed the previous FreeBSD behavior of using the first element for the egid. Any calls to setgroups() to clear groups that used a single array of the now or soon-to-be egid can be converted to setgroups(0, NULL) calls to clear the supplementary groups entirely on all FreeBSD versions.

| | | | | | | | | | | | | | | | | | | exit(3) is implemented by the runtime and performs a number of shutdown actions before ultimately calling _exit(2) to terminate the program. We historically named the syscall table entry `exit` rather than `_exit`, but this requires special handling in libc/libsys to cause the `_exit` symbol to exist while implementing `exit` in libc. Declare the syscall as `_exit` and flow that through the system. Because syscall(SYS_exit, code) is fairly widely used, allow a configured extra line in syscall.h to define SYS_exit to SYS__exit.
