better placement for dnssocket/dnsconnect

10 years ago

Move mutex, condvar, and thread-specific data routes, pthread_once, and pthread_exit from libpthread to libc, along with low-level bits to support them. Major bump to both libc and libpthread.

net

Switch if_nameindex(3) to use the new NET_RT_IFNAMES sysctl to get the list of interface names. At the same time switch if_nametoindex(3) and if_indextoname(3) to use if_nameindex(3) instead of getifaddrs(3). if_nameindex(3) exposes much less then getifaddrs(3) and is allowed by pledge(2).

netinet

Wrap <ifaddrs.h>, <netinet/in.h>, and <netinet/if_ether.h> so internal calls go direct and all the symbols are weak

10 years ago

rpc

Wrap <rpc/*.h> so that calls go direct and the symbols are all weak. Hide __xprt_register() and _authenticate(); truncate <rpc/svc_auth.h>

rpcsvc

Stop publicly declaring _yp_dobind() and struct dom_binding, closing out a rant Theo wrote 24 years ago. Mark __ypexclude_{add,is,free}() as hidden

sys

Add elf_aux_info(3)

2 years ago

_stdio.h

Modify the FILE object's members. Bump the libc major. Now we can bump the short members _file and _flags to int and drop the SHRT_MAX tests. Reorder the members, merge __sfileext into the object, switch the *printf and *scanf families from _FILEEXT_SETUP() to the FILEINIT() initializer, and update the allocation code in findfp(). Also, delete the __sF, _srget, and __swbuf symbols that remain from the previous step for our transition.

asr.h

Allow the caller of asr functions to create and use a specific context. Diff from eric@ and florian@, commiting on their behalf since they are absent and we want to ride the minor shlib bump.

assert.h

Wrap <assert.h> so that __assert2() goes direct

10 years ago

blf.h

Wrap blowfish, sha*, md5, and rmd160 so that internal calls go direct

10 years ago

bsd_auth.h

libc's authentication privsep layer performed insufficient username validation. Repair work mostly by markus and millert, first of all solving the primary problem, then adding some additional validation points. And then futher validation in login and su. This will be 6.5/021_libcauth.patch.sig and 6.6/010_libcauth.patch.sig Reported by Qualys

6 years ago

ctype.h

New POSIX xlocale implementation written from scratch. Complete in the sense that all POSIX *locale(3) and *_l(3) functions are included, but in OpenBSD, we of course only really care about LC_CTYPE and we only support ASCII and UTF-8.

db.h

Remove dead support for changing BDB hash algorithm and cache of alternatives

10 years ago

dirent.h

Add scandirat(3); from freebsd

2 years ago

dlfcn.h

Correct error returns, do not print eror message to stdout (there is a dlerror() function for that) and mark dladdr() as PROTO_NORMAL to be able to call it from a malloc.c MALLOC_STATS leak reporting project I'm working on. ok kettenis@

5 years ago

err.h

Pull in namespace.h when building all .c files using gcc's -include option, so that we can provide asm labels for the memcpy/memset/__stack_smash_handler calls that it generates ab initio. Eliminate direct #includes of it. Make sure it's a dependency of all objects (unnecessary for asm, but close enough).

10 years ago

errno.h

Use a Thread Information Block in both single and multi-threaded programs. This stores errno, the cancelation flags, and related bits for each thread and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable!

10 years ago

fcntl.h

Use a Thread Information Block in both single and multi-threaded programs. This stores errno, the cancelation flags, and related bits for each thread and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable!

10 years ago

float.h

Make sure attributes are applied to function declarations before they're used or defined, as clang isn't as forgiving as gcc. Also, declare __flt_rounds() so that libc can build it despire clang providing its own <float.h>

9 years ago

fstab.h

Wrap <fstab.h> so that calls go direct and the symbols are all weak (Do you sense a theme?)

10 years ago

fts.h

Wrap <fts.h> and <ftw.h> so that internal calls to fts_*() go direct and fts_*(), ftw(), and nftw() are weak symbols

ftw.h

Wrap <fts.h> and <ftw.h> so that internal calls to fts_*() go direct and fts_*(), ftw(), and nftw() are weak symbols

getopt.h

Don't wrap initialized variables: binutils appears to be mishandling them on arm and m88k

10 years ago

grp.h

Add uid_from_user() and gid_from_group(), derived from pax's cache.c. It replaces the existing pwcache.c functions user_from_uid(3) and group_from_gid(3) with the pax equivalents. Adapted from NetBSD (mycroft) changes from our own pax's cache.c. OK guenther@

icdb.h

Wrap <icdb.h> so that calls go direct and the symbols are all weak

10 years ago

ieeefp.h

Wrap fpgetround() so internal calls to it (seen on arm, powerpc, and sh) go direct instead of through the PLT.

ifaddrs.h

Wrap <ifaddrs.h>, <netinet/in.h>, and <netinet/if_ether.h> so internal calls go direct and all the symbols are weak

10 years ago

inttypes.h

Wrap <inttypes.h> and finish wrapping of <wchar.h> so that calls go direct and the symbols not in the C standard are weak

10 years ago

langinfo.h

New POSIX xlocale implementation written from scratch. Complete in the sense that all POSIX *locale(3) and *_l(3) functions are included, but in OpenBSD, we of course only really care about LC_CTYPE and we only support ASCII and UTF-8.

8 years ago

link_elf.h

Complete the ld.so boot cleanup: move most libc initialization from _csu_finish() to _libc_preinit(), which is an .init_array function in shared libc (and mark it INITFIRST) or a .preinit_array function in static libc, grabbing the _dl_cb callback there from ld.so. Then in _csu_finish(), invoke the dl_clean_boot() callback to free ld.so's startup bits before main() gets control.

locale.h

New POSIX xlocale implementation written from scratch. Complete in the sense that all POSIX *locale(3) and *_l(3) functions are included, but in OpenBSD, we of course only really care about LC_CTYPE and we only support ASCII and UTF-8.

login_cap.h

secure_path(3) hasn't been called since we recognized the TOCTOU issues a few years back, so we can remove it. Since nothing in the ecosystem calls it, I am not cranking the libc major as required, surely another crank will come along soon. noticed by Dante Catalfamo ok millert

4 years ago

math.h

Wrap the remaining math functions in libc: __fpclassify*(), __flt_rounds(), and ldexp().

10 years ago

md5.h

namespace.h is pulled in via -include, so don't do it here

sha1.h

Wrap blowfish, sha*, md5, and rmd160 so that internal calls go direct

10 years ago

sha2.h

Add functions for SHA512/256. The standard says you're supposed to start with different magic numbers, so we need to add some functions instead of just asking the user to truncate as desired. Sigh. SHA512 is quite a bit faster than SHA256 on 64 bit CPUs, but 256 bit hashes are usually quite sufficient. Best of both. ok deraadt tom

signal.h

Move sigwait(3) from libpthread to libc

7 years ago

siphash.h

Wrap blowfish, sha*, md5, and rmd160 so that internal calls go direct

10 years ago

softfloat.h

Make softfloat's internal float_raise also available under a hidden, internal name, so that local references to it do not need to go through the plt. (this routine is used by libm and thus can't be made internal to libc)

10 years ago

spawn.h

Wrap <spawn.h> to make all the symbols there weak

stdio.h

Modify the FILE object's members. Bump the libc major. Now we can bump the short members _file and _flags to int and drop the SHRT_MAX tests. Reorder the members, merge __sfileext into the object, switch the *printf and *scanf families from _FILEEXT_SETUP() to the FILEINIT() initializer, and update the allocation code in findfp().

stdio_ext.h

Add <stdio_ext.h> with the seven APIs needed to have gnulib operate without poking directly into the FILE structure.

2 years ago

stdlib.h

Add mkdtemps(3), like mkdtemp(3) but with a suffix. OK deraadt@ tb@

2 years ago

string.h

Instead of trying to handle ffs() with the normal rename-mark-hidden-and-alias dance, mark it protected. This works better for both gcc and clang: gcc blocks overriding of internal calls, while clang permits inlining again.

syslog.h

Declare sendsyslog to match its man page

2 years ago

termios.h

Use PROTO_DEPRECATED() make tcdrain() weak in libc, to guarantee libpthread can override it

tib.h

spelling fixes; from paul tagliamonte any changes not taken noted on tech, but chiefly here i did not take the cancelation - cancellation changes;

time.h

Add support for timeconting in userland.

ttyent.h

Wrap <ttyent.h> so that calls go direct and the symbols are all weak.

uchar.h

Provide C11 <uchar.h>. OK millert@. Tested by naddy@ in a bulk and by matthieu@ in the new foot(1) port. I originally wrote the code in 2022 at the prodding of espie@. Using one improvement to a manual page from jmc@.

2 years ago

unistd.h

Add pathconfat(2): pathconf(2) but with at-fd and flags arguments, the latter supporting the ability to get timestamp resolution of symlinks.

utime.h

Wrap <utime.h> to make utime() a weak symbol

uuid.h

Wrap <uuid.h> so that calls go direct and the symbols are all weak

vis.h

Wrap <vis.h> so that calls go direct and the symbols are all weak

10 years ago

wchar.h

Make the FILE object opaque. Move the __sFILE definition into libc/hidden/_stdio.h. All programs that refer to the internal structure of the FILE object can't be compiled from now on. std{in,out,err} doesn't refer __sF[] now, but the hidden __sF along with __srget and __swbuf symbols are kept temporarily to make our transition easier. But those symbols will be deleted soon. The shared library versions are bumped for libc and all the other libraries that refer to std{in,out,err}.

8 months ago

wctype.h

Simplify wctype() and wctype_l(): we have one set of classification types used by all (== both) locales; put their implementation in one file and make the mapping static there. The rl_wctype member of _RuneLocale and its initialization go away at the same time.
