* | race condition fix: block all signals before decrementing thread count | Rich Felker | 2011-02-19 | 3 | -22/+2 |
| | | | | | | | | | | | | the existence of a (kernelspace) thread must never have observable effects after the thread count is decremented. if signals are not blocked, it could end up handling the signal for rsyscall and contributing towards the count of threads which have changed ids, causing a thread to be missed. this could lead to one thread retaining unwanted privilege level. this change may also address other subtle race conditions in application code that uses signals. | ||||
* | make pthread_exit run dtors for last thread, wait to decrement thread count | Rich Felker | 2011-02-19 | 1 | -3/+3 |

* | add pthread_atfork interface | Rich Felker | 2011-02-18 | 1 | -0/+48 |
| | | | | | | | | | note that this presently does not handle consistency of the libc's own global state during forking. as per POSIX 2008, if the parent process was threaded, the child process may only call async-signal-safe functions until one of the exec-family functions is called, so the current behavior is believed to be conformant even if non-ideal. it may be improved at some later time. | ||||
* | reorganize pthread data structures and move the definitions to alltypes.h | Rich Felker | 2011-02-17 | 23 | -83/+83 |
| | | | | | | | | this allows sys/types.h to provide the pthread types, as required by POSIX. this design also facilitates forcing ABI-compatible sizes in the arch-specific alltypes.h, while eliminating the need for developers changing the internals of the pthread types to poke around with arch-specific headers they may not be able to test. | ||||
* | patch by njk, simplifies thread register initialization for x86_64 | Rich Felker | 2011-02-16 | 1 | -4/+0 |
| | | | | | It's not necessary to save any registers on the stack across syscall in x86_64 __set_thread_area. Don't waste cycles or bytes on it. | ||||
* | patch from njk: make x86_64 __uniclone branchless. | Rich Felker | 2011-02-16 | 1 | -6/+6 |
