Overflow detection in ngx_inet_addr().

2015-03-16T21:26:22+00:00

Core: overflow detection in ngx_parse_time() (ticket #732).

2015-03-16T21:26:20+00:00

Refactored ngx_parse_time().

2015-03-16T21:26:18+00:00

No functional changes.

Core: overflow detection in number parsing functions.

2015-03-16T21:26:15+00:00

Core: expose maximum values of time_t and ngx_int_t.

2015-03-16T21:24:34+00:00

These are needed to detect overflows.

Core: fixed potential buffer overrun when initializing hash.

2015-02-24T15:37:14+00:00

Initial size as calculated from the number of elements may be bigger
than max_size.  If this happens, make sure to set size to max_size.

Reported by Chris West.

Core: fixed a race resulting in extra sem_post()'s.

2015-02-04T13:22:43+00:00

The mtx->wait counter was not decremented if we were able to obtain the lock
right after incrementing it.  This resulted in unneeded sem_post() calls,
eventually leading to EOVERFLOW errors being logged, "sem_post() failed
while wake shmtx (75: Value too large for defined data type)".

To close the race, mtx->wait is now decremented if we obtain the lock right
after incrementing it in ngx_shmtx_lock().  The result can become -1 if a
concurrent ngx_shmtx_unlock() decrements mtx->wait before the added code does.
However, that only leads to one extra iteration in the next call of
ngx_shmtx_lock().

Resolver: fixed use-after-free memory access.

2014-11-20T12:24:40+00:00

In 954867a2f0a6, we switched to using resolver node as the
timer event data, so make sure we do not free resolver node
memory until the corresponding timer is deleted.

Core: fixed buffer overrun when hash max_size reached.

Version bump.
