I don't think we need the trailing two U16:#; on these. You use those to skip bits that you need to.

(or peel off the band-aid, whatever floats your boat) This addresses two separate issues: 1.) Nothing within bsdgrep actually knew whether it cared about line numbers or not. 2.) The file layer knew nothing about the context in which it was being called. #1 is only important when we're *not* processing line-by-line. #2 is debatably a good idea; the parsing context is only handy because that's where we store current offset information and, as of this commit, whether or not it needs to be line-aware.
Currently NMIs are sent over event channels, but that defeats the purpose of NMIs since event channels can be masked. Fix this by issuing NMIs using a hypercall, which injects a NMI (vector #2) to the desired vCPU. Note that NMIs could also be triggered using the emulated local APIC, but using a hypercall is better from a performance point of view since it doesn't involve instruction decoding when not using x2APIC mode.

Since then, no way has been found or demonstrated to reliably test the behavior, so remove the test. r332805: bsdgrep: Split match processing out of procfile procfile is getting kind of hairy, and it's not going to get better as we correct some more bits that assume we process one line at a time. r332806: bsdgrep: Clean up procmatches a little bit r332809: bsdgrep: Add some TODOs for future work on operating on chunks r332832: bsdgrep: Break procmatches down a little bit more Split the matching and non-matching cases out into their own functions to reduce future complexity. As the name implies, procmatches will eventually process more than one match itself in the future. r332850: bsdgrep: Some light cleanup There's no point checking for a bunch of file modes if we're not a practicing believer of DIR_SKIP or DEV_SKIP. This also reduces some style violations that were particularly ugly looking when browsing through. r332851: bsdgrep: More trivial cleanup/style cleanup We can avoid branching for these easily reduced patterns r332852: bsdgrep: if chain => switch This makes some of this a little easier to follow (in my opinion). r332856: bsdgrep: Fix --include/--exclude ordering issues Prior to r332851: * --exclude always win out over --include * --exclude-dir always wins out over --include-dir r332851 broke that behavior, resulting in: * First of --exclude, --include wins * First of --exclude-dir, --include-dir wins As it turns out, both behaviors are wrong by modern grep standards- the latest rule wins. e.g.: `grep --exclude foo --include foo 'thing' foo` foo is included `grep --include foo --exclude foo 'thing' foo` foo is excluded As tested with GNU grep 3.1. This commit makes bsdgrep follow this behavior. r332858: bsdgrep: Use grep_strdup instead of grep_malloc+strcpy r332876: bsdgrep: Fix build failure WITHOUT_LZMA (incorrect bracket placement) r333351: bsdgrep: Allow "-" to be passed to -f to mean "standard input" A version of this patch was originally sent to me by se@, matching behavior from newer versions of GNU grep. While there have been some differences of opinion on whether stdin should be closed or not after depleting it in process of -f, I've opted to leave stdin open and just let the later matching stuff fail and result in a no-match. I'm not married to the current behavior- it was generally chosen since we are adopting this in particular from GNU grep, and I would like to stay consistent without a strong argument to the contrary. The current behavior isn't technically wrong, it's just fairly unfriendly to the developer-user of grep that may not realize their usage is trivially invalid. r334803: netbsd-tests: grep(1): Add test for -c flag Someone might be inclined to accidentally break this. someone might have written said test because they broke it locally. r334806: bsdgrep(1): Do some less dirty things with return types Neither procfile nor grep_tree return anything meaningful to their callers. None of the callers actually care about how many lines were matched in all of the files they processed; it's all about "did anything match?" This is generally just a light refactoring to remind me of what actually matters as I'm rewriting these bits to care less about 'stuff'. r334807: bsdgrep(1): whoops, garbage collect the now write-only variable r334808: bsdgrep(1): Don't initialize fts_flags twice Admittedly, this is a clang-scan complaint... but it wasn't wrong. fts_flags is initialized by all cases in the switch(), which should be fairly obvious. Annotate this anyways. r334809: netbsd-tests: bsdgrep(1): Add a test for -m, too r334821: bsdgrep(1): Slooowly peel away the chunky onion (or peel off the band-aid, whatever floats your boat) This addresses two separate issues: 1.) Nothing within bsdgrep actually knew whether it cared about line numbers or not. 2.) The file layer knew nothing about the context in which it was being called. #1 is only important when we're *not* processing line-by-line. #2 is debatably a good idea; the parsing context is only handy because that's where we store current offset information and, as of this commit, whether or not it needs to be line-aware. r334837: bsdgrep(1): Evict character sequence that moved in r334889: bsdgrep(1): Some more int -> bool conversions and name changes Again motivated by upcoming work to rewrite a bunch of this- single-letter variable names and slightly misleading variable names ("lastmatches" to indicate that the last matched) are not helpful. r335188: bsdgrep(1): Remove redundant initialization; unconditionally assigned later r351769: bsdgrep(1): add some basic tests for some GNU Extension support These will be expanded later as I come up with good test cases; for now, these seem to be enough to trigger bugs in base gnugrep and expose missing features in bsdgrep. r352691: bsdgrep(1): various fixes of empty pattern/exit code/-c behavior When an empty pattern is encountered in the pattern list, I had previously broken bsdgrep to count that as a "match all" and ignore any other patterns in the list. This commit rectifies that mistake, among others: - The -v flag semantics were not quite right; lines matched should have been counted differently based on whether the -v flag was set or not. procline now definitively returns whether it's matched or not, and interpreting that result has been kicked up a level. - Empty patterns with the -x flag was broken similarly to empty patterns with the -w flag. The former is a whole-line match and should be more strict, only matching blank lines. No -x and no -w will will match the empty string at the beginning of each line. - The exit code with -L was broken, w.r.t. modern grep. Modern grap will exit(0) if any file that didn't match was output, so our interpretation was simply backwards. The new interpretation makes sense to me. Tests updated and added to try and catch some of this. This misbehavior was found by autoconf while fixing ports found in PR 229925 expecting either a more sane or a more GNU-like sed.

For this reason, define vop_close for zfsctl_ops_snapshot. While here, define vop_open for consistency. After adding the necessary vop, the bug progresses to the following panic: panic: VERIFY3(vrecycle(vp) == 1) failed (0 == 1) cpuid = 17 KDB: stack backtrace: #0 0xffffffff805e29c5 at kdb_backtrace+0x65 #1 0xffffffff8059620f at vpanic+0x17f #2 0xffffffff81a27f4a at spl_panic+0x3a #3 0xffffffff81a3a4d0 at zfsctl_snapshot_inactive+0x40 #4 0xffffffff8066fdee at vinactivef+0xde #5 0xffffffff80670b8a at vgonel+0x1ea #6 0xffffffff806711e1 at vgone+0x31 #7 0xffffffff8065fa0d at vfs_hash_insert+0x26d #8 0xffffffff81a39069 at sfs_vgetx+0x149 #9 0xffffffff81a39c54 at zfsctl_snapdir_lookup+0x1e4 #10 0xffffffff80661c2c at lookup+0x45c #11 0xffffffff80660e59 at namei+0x259 #12 0xffffffff8067e3d3 at kern_statat+0xf3 #13 0xffffffff8067eacf at sys_fstatat+0x2f #14 0xffffffff808b5ecc at amd64_syscall+0x10c #15 0xffffffff8088f07b at fast_syscall_common+0xf8 This is caused by a race condition that can occur when allocating a new vnode and adding that vnode to the vfs hash. If the newly created vnode loses the race when being inserted into the vfs hash, it will not be recycled as its usecount is greater than zero, hitting the above assertion. Fix this by dropping the assertion.

Avoid locking issues when if_allmulti() calls the driver's if_ioctl, because that may acquire sleepable locks (while we hold a non-sleepable rwlock). Fortunately there's no pressing need to hold the mroute lock while we do this, so we can postpone the call slightly, until after we've released the lock. This avoids the following WITNESS warning (with iflib drivers): lock order reversal: (sleepable after non-sleepable) 1st 0xffffffff82f64960 IPv4 multicast forwarding (IPv4 multicast forwarding, rw) @ /usr/src/sys/netinet/ip_mroute.c:1050 2nd 0xfffff8000480f180 iflib ctx lock (iflib ctx lock, sx) @ /usr/src/sys/net/iflib.c:4525 lock order IPv4 multicast forwarding -> iflib ctx lock attempted at: #0 0xffffffff80bbd6ce at witness_checkorder+0xbbe #1 0xffffffff80b56d10 at _sx_xlock+0x60 #2 0xffffffff80c9ce5c at iflib_if_ioctl+0x2dc #3 0xffffffff80c7c395 at if_setflag+0xe5 #4 0xffffffff82f60a0e at del_vif_locked+0x9e #5 0xffffffff82f5f0d5 at X_ip_mrouter_set+0x265 #6 0xffffffff80bfd402 at sosetopt+0xc2 #7 0xffffffff80c02105 at kern_setsockopt+0xa5 #8 0xffffffff80c02054 at sys_setsockopt+0x24 #9 0xffffffff81046be8 at amd64_syscall+0x138 #10 0xffffffff8101930b at fast_syscall_common+0xf8 See also: https://redmine.pfsense.org/issues/12079 Reviewed by: mjg Sponsored by: Rubicon Communications, LLC ("Netgate") Differential Revision: https://reviews.freebsd.org/D41209
Specifically, altering the console list with conscontrol has some weird behavior: 1. If you remove the first configured console, /dev/console will become unconfigured 2. Any console added becomes the /dev/console In a multicons situation, #1 is clearly a bug and #2 is perhaps slightly less clear. If we have ttyu0, ttyv0, then it seems obvious that one would want ttyv0 to take over the console if ttyu0 is removed. If we add ttyu0 back in, then it's debatable whether it should take over the console or not. Fix it now to make the /dev/console selection more FIFO-ish, with respect to how conscontrol affects it. A `primary` verb for conscontrol(8) might be a good addition.
