* Stop inlining the struct ucond definition into struct pthread_cond.Konstantin Belousov2016-05-292-15/+11
| | | | | | | | | | | | | | | | | | | | This avoids unneccessary casts and make the calls to _thr_ucond_*() functions less questionable. The c_spare field was not included into struct pthread_cond, so the change modifies libthr ABI for shared condvars. But since an off-page does not legitimately contains any other data past the struct pthread_cond, the change keeps shared condvars from pre- and post- changed libthr compatible. Also note that the whole struct ucond was never copied in or out by kernel. For private condvars, the privately allocated memory was never exposed outside libthr.

It had a number of problems: It was only being emitted on a transition to the HEALTHY state. That made it impossible for zfsd to take actions based on drives getting sicker. It compared the new state to vdev_prevstate, which is the state that the vdev had the last time it was opened. That doesn't make sense, because a vdev can change state multiple times without being reopened. vdev_set_state contains logic that will change the device's new state based on various conditions. However, the statechange event was being posted _before_ that logic took effect. Now it's being posted after.

* Implement SHA-512 truncated (224 and 256 bits)Allan Jude2016-05-284-10/+78
| | | | | | | | | | | | | | | | | | | | | | This implements SHA-512/256, which generates a 256 bit hash by calculating the SHA-512 then truncating the result. A different initial value is used, making the result different from the first 256 bits of the SHA-512 of the same input. SHA-512 is ~50% faster than SHA-256 on 64bit platforms, so the result is a faster 256 bit hash. The main goal of this implementation is to enable support for this faster hashing algorithm in ZFS. The feature was introduced into ZFS in r289422, but is disconnected because SHA-512/256 support was missing. A further commit will enable it in ZFS.

| | | | | | | | | | | | | | | | | Though the buffer used by l64a() is initialized with null bytes, repetetive calls may end up having trailing garbage of previous invocations because we don't end up terminating the string. Instead of importing NetBSD's fix, use this opportunity to simplify this function dramatically, for example by just storing the Base64 character set in a string. There is also no need to do the bitmasking, as we can just use the proper integer type from <stdint.h>.

All instances generate an Out-of-bounds access (ARRAY_VS_SINGLETON) error because of the treatment of the header as a two element array, with a pointer to the non-existent second element being passed as the starting address to bzero(). Some instances also alsp generate Out-of-bounds access (OVERRUN) errors, probably because the space being cleared is larger than the sizeofstruct ccb_hdr). In addition, this idiom is difficult for humans to understand and it is error prone. The user has to chose the proper struct ccb_* type (which does not appear in the surrounding code) for the sizeof() in the length calculation. I found several instances where the length was incorrect, which could cause either an actual out of bounds write, or incompletely clear the ccb. A better way is to write the code to clear the ccb itself starting at sizeof(ccb_hdr) bytes from the start of the ccb, and calculate the length based on the specific type of struct ccb_* being cleared as specified by the union ccb member being used. The latter can normally be seen in the nearby code. This is friendlier for Coverity and other static analysis tools because they will see that the intent is to clear the trailing part of the ccb. Wrap all of the boilerplate code in a convenient macro that only requires a pointer to the desired union ccb member (or a pointer to the union ccb itself) as an argument.

* | libc/regex: fix two buffer underruns.Pedro F. Giffuni2016-05-211-9/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix some rather complex regex issues found on OpenBSD as part of some ongoing work to fix a sed(1) bug. Curiously the OpenBSD tests don't trigger segfaults on FreeBSD but the bugs were confirmed by running a port of FreeBSD's regex under OpenBSD's malloc. Huge thanks to Ingo for confirming the behavior. Taken from: Ingo Schwarze (through openbsd-tech 2016-05-15) MFC after: 1 week Notes: svn path=/head/; revision=300378
* | Add FREEBSD_CC_VERSION which will be used to define __FreeBSD_cc_version.Bryan Drewery2016-05-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The WITH_SYSTEM_COMPILER build option will rely on this value to determine what __FreeBSD_cc_version the source tree will produce. This value will be compared against the /usr/bin/cc value to determine if a new compiler is needed. Start with 1100002 which is 1 more than than the value we've had since 3.8.0 to ensure that all changes since then are present.

* | Remove brk and sbrk from arm64. They were defined in The Single UNIXAndrew Turner2016-05-204-155/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Specification, Version 2, but marked as legacy, and have been removed from later specifications. After 12 years it is time to remove them from new architectures when the main use for sbrk is an invalid method to attempt to find how much memory has been allocated from malloc. There are a few places in the tree that still call sbrk, however they are not used on arm64. They will need to be fixed to cross build from arm64, but these will be fixed in a follow up commit. Old copies of binutils from ports called into sbrk, however this has been fixed around 6 weeks ago. It is advised to update binutils on arm64 before installing a world that includes this change.
