bf351925f7 Typo seek(2) -> lseek(2) 2001-09-02 19:24:07 +00:00
Andrey A. Chernov
924888f977 Move all stdio internal flags processing and setting out of __sread(),
__swrite() and __sseek() to higher level. According to funopen(3) they all
are just wrappers to something like standard read(2), write(2) and
lseek(2), i.e. must not touch stdio internals because they are replaceable
with any other functions knows nothing about stdio internals. See example
of funopen(3) usage in sendmail sources f.e.

NOTE: this is original stdio bug, not result of my range checkin added.

35e1a550de Save errno before function call and restore it on success (because many
internal functions there may fail and set (i.e. overwrite) errno in normal
(not error) situation). In original variant errno testing after call
(as POSIX suggest) is wrong when errno overwrite happens.

65efd81290 Back out disabling ungetc() at 0, use different solution:
keep negative offset internally, but return 0 externally in ftell*()
I.e. use 0 now as 'unspecified value' per POSIX ungetc() description.

support functions:
     cap_subset_np()    - Is cap1 a subset of cap2
     cap_equal_np()     - Is cap1 equal to cap2

o Introduce implementations of POSIX.1e capability support functions:
     cap_copy_ext()     - Externalize capability
     cap_copy_int()     - Internalize capability
     cap_size()         - Determine size required for cap_copy_ext()

e54bc118c1 Add more EOVERFLOW checks.
When file offset tends to be negative due to internal and ungetc buffers
additions counted, try to discard some ungetc data first, then return EBADF.
Later one can happens if lseek(fileno(fd),...) called f.e. POSIX says that
ungetc beyond beginning of the file results are undefined, so we can just
discard some of ungetc data in that case.

Don't rely on gcc cast when checking for overflow, use OFF_MAX.

Cosmetique.

03516cfeb0 o Remove some GCCisms in src/powerpc/include/endian.h.
o Unify <machine/endian.h>'s across all architectures.
o Make bswapXX() functions use a different spelling of u_int16_t and
  friends to reduce namespace pollution.  The bswapXX() functions
  don't actually exist, but we'll probably import these at some
  point.  Atleast one driver (if_de) depends on bswapXX() for big
  endian cases.
o Deprecate byteorder(3) prototypes from <sys/types.h>, these are
  now prototyped indirectly in <arpa/inet.h>.
o Deprecate in_addr_t and in_port_t typedefs in <sys/types.h>, these
  are now typedef'd in <arpa/inet.h>.
o Change byteorder(3) prototypes to use standards compliant uint32_t
  (spelled __uint32_t to reduce namespace pollution).
o Document new preferred headers and standards compliance.

fca41b9c6f o src/sys/capability.h provides a number of support macros that are not
documented by POSIX.1e, and understand the opaque capability structures.
  Introduce support in the userland POSIX.1e library for a
  _CAPABILITY_NEEDMACROS define to remove these macros from the normal
  namespace, but allow the libc functions to use them.

5cb74fd363 Ok, third time is the charm. VM_INHERIT_XXX -> INHERIT_XX (use the same

dbad546ba7 Update the mmap.2 and minherit.2 manual pages. Add a short explanation and
referal from mmap to minherit for MAP_INHERIT.  Fully document the
minherit.2 manual page (because frankly, my dear, however you think it
currently works is almost certainly wrong!).  I may soon re-implement
MAP_COPY because I believe we can support it properly now, but I will have
to call it something else and that is for a later time.
