descriptor was set by dataconn(). this fixes a problem for clients (such
as lynx and netscape) that only sent PASV/EPSV after a transfer (RETR, LIST,
STOR) started and returned 150. certain command sequences could return 550
(etc) before setting up the dataconn(), and would run into this bug. netbsd's
ftp didn't hit this bug because it always sends PASV/EPSV before a new
transfer command.
- change error checking philosophy: instead of returning errors to the
upper layer only to fail silently and exit there, or die of unexpected
NULL pointers bail out and print an error immediately. Add emalloc/estrdup
to simplify. This change removed a bunch of code.
- fix size_t/int confusion
- cast argument to isspace(3) to unsigned char
- ? : statement is not an lvalue, so don't take its address.
- unlink the file before we open it, because we chmod it to readonly.
- misc KNF
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".
- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.
- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs
* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz
* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.
* Always install /sbin/init statically (for now)
The net effect of these changes depends on how the variables are set:
1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so
2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so
3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed
thus isolating the "iffy hueristic" from the rest of the relocation code.
* In the "iffy hueristic", use _GOT_END_, not _DYNAMIC.
* Include the addend in Alpha R(RELATIVE) relocations.
