* login(1): when exporting variables check the result of setenv(3)Pedro F. Giffuni2020-12-191-1/+4
| | | | | | | | | | | | | | | When exporting a variable we correctly check all the preconditions that could make setenv(3) fail. Checking the setenv(3) return value seems redundant, but given that login(1) is critical, it doesn't hurt to have a post-check.

* fts_read: Handle error from a NULL return better.Bryan Drewery2020-12-083-3/+7
| | | | | | | | | | | | | | | | | | | | This is addressing cases such as fts_read(3) encountering an [EIO] from fchdir(2) when FTS_NOCHDIR is not set. That would otherwise be seen as a successful traversal in some of these cases while silently discarding expected work. As noted in r264201, fts_read() does not set errno to 0 on a successful EOF so it needs to be set before calling it. Otherwise we might see a random error from one of the iterations. gzip is ignoring most errors and could be improved separately.

| | | | | | | | | | | | | | | | | r368355 removed the GNU_GREP_COMPAT knob (off by default) and forgot that bsdgrep may be built/used for bootstrap on some systems. All base uses should strive to use only POSIX-compliant expressions anyways and we haven't had libregex by default here up to this point, so just don't do that if we're bootstrapping. Note that the resulting binary has the wrong `grep -V` information as it falsely claims to be GNU compatible, but it is only for bootstrap.

* Remove the cloned file descriptors for /dev/crypto.John Baldwin2020-11-252-8/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Crypto file descriptors were added in the original OCF import as a way to provide per-open data (specifically the list of symmetric sessions). However, this gives a bit of a confusing API where one has to open /dev/crypto and then invoke an ioctl to obtain a second file descriptor. This also does not match the API used with /dev/crypto on other BSDs or with Linux's /dev/crypto driver. Character devices have gained support for per-open data via cdevpriv since OCF was imported, so use cdevpriv to simplify the userland API by permitting ioctls directly on /dev/crypto descriptors. To provide backwards compatibility, CRIOGET now opens another /dev/crypto descriptor via kern_openat() rather than dup'ing the existing file descriptor. This preserves prior semantics in case CRIOGET is invoked multiple times on a single file descriptor.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The program reads oldsize bytes from oldfile, and proceeds to initialize a suffix array of oldsize elements using divsufsort(). As per the function's API [1], array indices 0 through n-1 are initialized. Later, search() is called, but with index bounds [0, n]. Depending on the contents of the malloc'd buffer, accessing this uninitialized index at the end of can result in a segmentation fault. Fix this by passing oldsize-1 to search(), limiting the search bounds to [0, n-1]. This bug is a result of r303285, which introduced divsufsort() as an alternate suffix sorting function to the existing qsufsort(). It seems that qsufsort() did initialize the final empty element, meaning it could be safely accessed. This difference in the implementations was missed at the time.

Similar to ICU's ucol_getVersion() and Windows' GetNLSVersionEx(), this API is intended to allow databases to detect when text order-based indexes might need to be rebuilt. The CLDR version is extracted from CLDR source data by the Makefile under tools/tools/locale, written into the machine-generated Makefile under shared/colldef, passed to localedef -V, and then written into LC_COLLATE file headers. The initial version is 34.0. tools/tools/locale was recently updated to pull down 35.0, but the output hasn't been committed under share/colldef yet, so that will provide the first observable change when it happens. Other versioning schemes are possible in future, because the format is unspecified.
