2020-03-25Grab the NET_LOCK() before calling pipex_iface_stop().Martin Pieuchot
This function calls pipex_destroy_session() which requires the lock and pipex_ioctl() already calls it with the NET_LOCK() held. From Vitaliy Makkoveev.

2020-03-24Rename wsmousedoioctl() -> wmouse_do_ioctl() and follow the sameanton

2020-03-24Ensure that me_evp is still NULL before assignment during open of wsconsanton
devices. This condition is checked early on during open but since the same routine could end up sleeping before assigning me_evp, a race against adding the same wscons device to a wsmux could be lost. This in turn can cause a NULL deference during close. ok mpi@ Reported-by: syzbot+34c3041bfd96c888c8bd@syzkaller.appspotmail.com

2020-03-23Prevent tsleep(9) with PCATCH from returning immediately without errorVisa Hankala
when called during execve(2). This was a caused by initializing sls_sig with value 0 in r1.164 of kern_synch.c. Previously, tsleep(9) returned immediately with EINTR in similar circumstances. The immediate return without error can cause a system hang. For example, vwaitforio() could end up spinning if called during execve(2) because the thread did not enter sleep and other threads were not able to finish the I/O. tsleep vwaitforio nfs_flush nfs_close VOP_CLOSE vn_closefile fdrop closef fdcloseexec sys_execve Fix the issue by checking (p->p_flag & P_SUSPSINGLE) instead of (p->p_p->ps_single != NULL) in sleep_setup_signal(). The former is more selective than the latter and allows the thread that invokes execve(2) enter sleep normally. Bug report, change bisecting and testing help by Pavel Korovin OK claudio@ mpi@

so we can re-use the same mechanisms. It's not the same though, which means that some code is duplicated. There's some room for refactoring. The PLLs, on the other hand, work quite differently.

2020-03-20__thrsleep(2): fix absolute timeout checkcheloha
An absolute timeout T elapses when the clock has reached time T, i.e. when T is less than or equal to the clock's current time. But the current code thinks T elapses only when the clock is strictly greater than T. For example, if my absolute timeout is 1.00000000, the current code will not return EWOULDBLOCK until the clock reaches 1.00000001. This is wrong: my absolute timeout elapses a nanosecond prior to that point. So the timespeccmp(3) here should be timespeccmp(tsp, &now, <=) and not timespeccmp(tsp, &now, <) as it is currently.

2020-03-20tsleep_nsec(9): add MAXTSLP macro, the maximum sleep durationcheloha
This macro will be useful for truncating durations below INFSLP (UINT64_MAX) when converting from a timespec or timeval to a count of nanoseconds before calling tsleep_nsec(9), msleep_nsec(9), or rwsleep_nsec(9). A relative timespec can hold many more nanoseconds than a uint64_t can. TIMESPEC_TO_NSEC() and TIMEVAL_TO_NSEC() check for overflow, returning UINT64_MAX if the conversion would overflow a uint64_t. Thus, MAXTSLP will make it easy to avoid inadvertently passing INFSLP to tsleep_nsec(9) et al. when the caller intended to set a timeout. The code in such a case might look something like this: uint64_t nsecs = MIN(TIMESPEC_TO_NSEC(&ts), MAXTSLP); The macro may also be useful for rejecting intervals that are "too large", e.g. for sockets with timeouts, if the timeout duration is to be stored as a uint64_t in an object in the kernel. The code in such a case might look something like this: case SIOCTIMEOUT: { struct timeval *tv = (struct timeval *)data; uint64_t nsecs; if (tv->tv_sec < 0 || !timerisvalid(tv)) return EINVAL; nsecs = TIMEVAL_TO_NSEC(tv); if (nsecs > MAXTSLP) return EOVERFLOW; obj.timeout = nsecs; break; } Idea suggested by visa@. ok visa@
