Add description of `mc' (max copies), add short-form to long-form mapping
for `tf' (troff filter), and add a cross-reference to chkprintcap in some
lpr-related man pages.
Fix WAW dependency violation on r17 (line 198) that only exists for
the SMP case. While on the subject, remove unnecessary stops. I don't
know if this resolves the memory corruption I'm seeing, but it does
have the potential. We'll see...
Implement elf_reloc(). The RT specification says that we can expect
both Elf_Rel and Elf_Rela types of relocation, so handle them both
even though we only have Rel_Rela ATM. We don't handle 32-bit and
big-endian variants yet. Support for that is not trivial enough to
implement it without any evidence that we ever need it in the near
future.
For the FPTR relocations, we currently use the fptr_storage used by
_reloc() is locore.s. This is in no way a real solution, but for now
provides the service we need to get the basics going.
A static recursive function lookup_fdesc() is used to find the address
of a function in a way that keeps track of the load module so that
we can get the correct GP value if we need to construct an OPD (ie
there's no OPD yet for the function.
For simplicity, we create an OPD for the IPLT relocations as well and
simply fill the user provided function descriptor from the OPD. Since
the the official descriptors are unique, this has no bad side effects.
Note that we ignore the addend for FPTR relocations, but use the
addend for IPLT relocations as an offset to the function address.
This commit allows us to load and relocate modules and modules appear
to work correctly, although we probably need to make sure that we set
GP correctly in all cases when we have inter-module calls. This
especially applies to assembly coded functions that have cross module
calls.
Add function link_elf_get_gp(), specific to ia64 for now, to get
the DT_PLTGOT value. On ia64 this is the value of GP. We need this
to construct function descriptors, but the elf file structure is
not exported to MD code.
Note that the name of the function is based on the meaning that
DT_PLTGOT has on ia64. This may differ on other architectures. As
such, link_elf_get_gp() has a high level of MD to it. Renaming the
function to describe what DT_* value is returned makes it generic,
but also makes the MD code less clear and if we only need this on
ia64, then a general name for a specific function doesn't help.
In short: I don't know what is "right" at this time, so I'll go
with what I have.
Non-sendmail users use the FreeBSD sendmail startup functionality to start
alternative MTAs. Therefore, always install rc.sendmail, regardless of
NO_SENDMAIL make.conf setting. Users can still set mta_start_script to a
different script.
This commit is after a repo-copy of src/etc/sendmail/rc.sendmail to
src/etc/rc.sendmail.

Turn blank lines into .Pp . This does not significantly change the
rendering of the man pages (turns some sequences of two blank lines
into a single blank line), and eliminates 306 errors generated while
formatting named.conf.5 .
mdoc police: Use Em ("emphasis") to get italics/underlining, instead of
Sm Pa (a syntax error, and an assertion that the arguments are path
names, which is a little far from true).
Limit to the maximum allowed reply size the amount of data that
nfsrv_readdir and nfsrv_readdirplus can return. A client request
containing an over-large `count' field could trigger the "Bad nfs
svc reply" panic in nfs_syscalls.c.
Spotted while trying to reproduce kern/37304, which turned out to
be fixed in FreeBSD a long time ago.
Include <sys/systm.h> for (at least) the definition of atomic functions
which are sometimes used by the macros in <sys/mutex.h>; don't depend
on not-quite-necessary namespace pollution in <sys/mutex.h>.
Improve self-relocation:
o We don't expect the PLT relocations to follow the .rela section
anymore. We still assume that PLT relocations are long formed,
o Document register usage,
o Improve ILP,
o Fix the FPTR relocation by creating unique OPDs per function.
Comparing functions is valid now,
o The IPLT relocation naturally handles the addend. Deal with it.
We ignore the addend for FPTR relocations for now. It's not at
all clear what it means anyway.
Fix ABI misinterpretation:
o For Elf_Rela relocations, the addend is explicit and should not
be loaded from the memory address we're relocating. Only do that
for Elf_Rel relocations (ie the short form).
o DIR64LSB is not the same as REL64LSB. DIR64LSB applies to a
symbol (S+A), whereas REL64LSB applies to the base address (BD+A),
Tidy up some of the configs; s/gcc/cc/ to make the choice of C compiler
more generic. Fix paths for things like scripts (fix perldoc). Tweak
externally passed macros.
Add FBSDID. Start errx(3) messages with lowercase. Remove a ')' with no '('.
In usage(), use fprintf(3) instead of errx(3), to make the printed string really
start with `usage: ...'.

Don't load the netgraph line discipline. When it's in use, TIOCMGET
fails and on loss of carrier, the device doesn't become selectable with
0 bytes to read.
For the P function, the newline must be considered a part of the pattern
space, so when printing it, don't let the pattern space and the output run
into eachother by omitting the \n when printing.
Add sed(1) tests for proper behaviour of the G option as fixed in PR 26152,
and for proper behaviour of some sed functions given a nil pattern space,
as fixed in PR 34813.
The test for G was based on the test in the PR. The nil pattern space test
is slightly different as we need to get *some* output, as the core dump will
also produce no output (old behaviour) and turn up falsely that the utility
is working fine.
New release notes: UserConfig gone (release note long overdue!), kget(8)
gone, UDF support added, inetd(8) not run by default, inbound SMTP not
enabled by default.
Despite the fact that it is documented in the handbook, the release notes,
and UPDATING and has been posted to both freebsd-current and
freebsd-stable, users are still not adding the required smmsp user and
group before doing an installworld. Therefore, don't let users do an
installworld unless they have followed directions.
Add a new installcheck Makefile target which installworld runs before
actually starting the installation. This target can be used by other parts
of userland as well. The first addition to the target is to check for the
smmsp user and group if NO_SENDMAIL isn't defined.
Others may add checks to this target as they see fit.
Add an exceedingly simple regression test for the file2c program. One would
hope that it would never regress, but this is a straightforward test, so add
it.
In my continuing crusade to make life better for non-sendmail users, avoid
the creation of /var/spool/clientmqueue and therefore the need for the
smmsp user and group if NO_SENDMAIL is defined. This required breaking out
the creation of the directory into a new BSD.sendmail.dist mtree file.
Implement several of the c99 updates to scanf(3):
- New length modifiers: hh, j, ll, t, z.
Still to do:
- %C, %S, %lc, %ls (wide character support)
- %a/%A (exact hex representation of floating-point numbers)
Removed old compatability equivalents:
- %D for %ld, %O for %lo, %X for %lx, %E and %F for %le & %lf (these
were buggy anyway, since they should have represented %Le & %Lf).
- %[unknown uppercase char] for %ld, %[unknown lowercase char] for %d
Check the alignment of the stack pointer before copying in windows from the
user stack in response to a failed window fill, allowing the process to be
killed if its wrong. This caused user programs which misalign their stack
pointer to get stuck in an infinite loop at the kernel-userland boundary,
which is mostly harmless.
The same thing causes a fatal RED state exception on OpenBSD and probably
NetBSD.
Add an XXX: linux_uselib() should be using vn_open() rather than invoking
VOP_OPEN() and doing lots of manual checking. This would further
centralize use of the name functions, and once the MAC code is integrated,
meaning few extraneous MAC checks scattered all over the place. I don't
have time to fix this now, but want to make sure it doesn't get
forgotten. Anyone interested in fixing this should feel free.

Fix for the sshd(8) utmp problem. Previously, login(3) would ignore the tty
named by its argument and use ttyslot(3) instead to determine what slot to
use. The problem is that sshd(8) calls pam_open_session(3) before forking
the child (as it should), at which point it does not have a controlling
terminal. Also, ttyslot(3) is very crude as it assumes fd 0, 1 or 2 refers
to the controlling terminal, which is usually (but not always) the case.
Instead of using ttyslot(3) to determine the slot number, look up the
specified tty in /etc/ttys ourselves (this is what ttyslot(3) does anyway).
1) Surprisingly, "CheckMail" handling code completely removed from this
