Package: gnutls28
Version: 3.4.8-3
Severity: important
Hi,
gnutls28 tests/mini-loss-time fails about 20% of the time when I try it
on kfreebsd-amd64. I think probably introduced by this commit:
https://gitlab.com/gnutls/gnutls/commit/e2a3ad31c487cbce997a08dddc55db639b60c024
The failure happens at ~60 seconds elapsed, when some (expected) timeout
is reached. The child always exits first, and closes fds:
(49946 101730 = child)
49946 101730 mini-loss-time 60.187211 CALL close(0x4)
49946 101730 mini-loss-time 60.187244 RET close 0
49946 101730 mini-loss-time 60.187346 CALL close(0x3)
49946 101730 mini-loss-time 60.187363 RET close 0
49946 101730 mini-loss-time 60.187830 CALL exit(0)
The parent receives SIGCHLD, and some wait() call on the child pid
returns:
(49871 102302 = parent)
49871 102302 mini-loss-time 60.188448 RET select -1 errno 4 Interrupted
system call
49871 102302 mini-loss-time 60.188572 PSIG SIGCHLD caught handler=0x401570
mask=0x0 code=CLD_EXITED
49871 102302 mini-loss-time 60.188594 CALL wait4(0xffffffff,0x7fffffffdd44,0,0)
49871 102302 mini-loss-time 60.188657 RET wait4 49946/0xc31a
49871 102302 mini-loss-time 60.188673 CALL sigreturn(0x7fffffffdd70)
49871 102302 mini-loss-time 60.188689 RET sigreturn JUSTRETURN
49871 102302 mini-loss-time 60.188713 CALL clock_gettime(0,0x7fffffffe320)
49871 102302 mini-loss-time 60.188808 RET clock_gettime 0
49871 102302 mini-loss-time 60.188831 CALL clock_gettime(0,0x7fffffffe320)
49871 102302 mini-loss-time 60.188847 RET clock_gettime 0
In the successful case, the parent exits now.
In the failure case, the parent tries to read something from an fd
first, I guess a pipe that was just closed at the other end
(maybe the server didn't time out quite yet?) :
(50000 101614 = parent)
50000 101614 mini-loss-time 59.273668 CALL recvfrom(0x5,0x624833,0x415c,0,0,0)
50000 101614 mini-loss-time 59.273686 RET recvfrom -1 errno 54 Connection
reset by peer
leading to GNUTLS_E_PUSH_ERROR rather than expected GNUTLS_E_TIMEDOUT.
The attached ktrace dumps can be compared using vimdiff to help
study this. I haven't tested on GNU/Linux.
If I lower the server timeout to 29 seconds, I haven't seen this failure
any more.
