[Bug 246385] SIGCHLD dropped if generated while blocked in sigfastblock
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=246385 Bug ID: 246385 Summary: SIGCHLD dropped if generated while blocked in sigfastblock Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: b...@freebsd.org Reporter: corydo...@ridiculousfish.com Attachment #214394 text/plain mime type: Created attachment 214394 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=214394&action=edit reduced test case, see description for how to compile fish-shell is observing a hang under FreeBSD CURRENT which I believe to be a regression in FreeBSD signal handling, relative to 12.1. Originally reported as https://github.com/fish-shell/fish-shell/issues/6919 High level: if a process forks and the child exits before fork is complete in the parent, then SIGCHLD will not be delivered. Details: fork() will block signals using sigfastblock. If the child dies before signals are unblocked, the SIGCHLD will be marked as pending via the sigfastblock word. In this case fork() will issue a syscall to `sigfastblock(SIGFASTBLOCK_UNBLOCK)`; however SIGCHLD will NOT be delivered. Reduced test case attached as `demo.c`. This test case uses a loop which creates a child and waits for SIGCHLD to be delivered via the self-pipe trick. It counts every 256 iterations. To reproduce: clang demo.c ; ./a.out # this does not hang clang -lpthread demo.c ; ./a.out # this hangs on FreeBSD CURRENT only ktrace output: Good iteration (SIGCHLD generated while signals NOT blocked): 27181 a.outCALL fork 27181 a.outRET fork 27581/0x6bbd 27181 a.outCALL read(0x3,0x7fffe8e0,0x200) 27181 a.outRET read RESTART 27181 a.outPSIG SIGCHLD caught handler=0x800258dd0 mask=0x0 code=CLD_EXITED 27181 a.outCALL sigprocmask(SIG_SETMASK,0x7fffe24c,0) 27181 a.outRET sigprocmask 0 27181 a.outCALL write(0x4,0x7fffde6b,0x1) 27181 a.outGIO fd 4 wrote 1 byte 27181 a.outRET write 1 27181 a.outCALL sigreturn(0x7fffde80) 27181 a.outRET sigreturn JUSTRETURN 27181 a.outCALL read(0x3,0x7fffe8e0,0x200) 27181 a.outGIO fd 3 read 1 byte Hanging iteration (SIGCHLD generated while signals ARE blocked): 27181 a.outRET read 1 27181 a.outCALL wait4(0x6bbd,0x7fffe8d4,0x6,0) 27181 a.outRET wait4 27581/0x6bbd 27181 a.outCALL fork 27181 a.outRET fork 27582/0x6bbe 27181 a.outCALL sigfastblock(0x2,0) 27181 a.outRET sigfastblock 0 27181 a.outCALL read(0x3,0x7fffe8e0,0x200) Note the call to sigfastblock(0x2) (pending signal) but PSIG SIGCHLD is not generated. -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"

[Bug 246413] boot from 12.1 DVD iso as MBR causes panic zfree wild pointer

My W520 lenovo thinkpad tries MBR boot before UEFI boot from DVD. Booting as MBR causes the panic. If I change the BIOS to try UEFI before MBR it works fine. The workaround for 242106 is to tell the VM to boot UEFI first. The text of the panic is: CD Loader 1.2 Building the boot loader arguments Looking up /BOOT/LOADER... found Relocating the loader and BTX Starting the BTX loader BTX loader 1.00 BTX version is 1.02 Consoles: internal video/keyboard BIOS CD is cd0 BIOS drive C: is disk0 BIOS 630kb/3125884kb available memory FreeBSD/x86 bootstrap loader, Revision 1.1 panic: zfree(90xbd69c6b0,8224): wild pointer --> Press a key on the console to reboot <-- I reproduced this with disk and dvd ISO's The code should probably sanity check the startup environment.
