If the format string contains %m, clearly errno must have a meaningful
value, so we might as well use log_*_errno to have ERRNO= logged.
Using:
find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/'
Plus some whitespace, linewrap, and indent adjustments.
Using:
find . -name '*.[ch]' | while read f; do perl -i.mmm -e \
'local $/;
local $_=<>;
s/(if\s*\([^\n]+\))\s*{\n(\s*)(log_[a-z_]*_errno\(\s*([->a-zA-Z_]+)\s*,[^;]+);\s*return\s+\g4;\s+}/\1\n\2return \3;/msg;
print;'
$f
done
And a couple of manual whitespace fixups.
As a followup to 086891e5c1 "log: add an "error" parameter to all
low-level logging calls and intrdouce log_error_errno() as log calls
that take error numbers", use sed to convert the simple cases to use
the new macros:
find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/'
Multi-line log_*() invocations are not covered.
And we also should add log_unit_*_errno().
- Rename log_meta() → log_internal(), to follow naming scheme of most
other log functions that are usually invoked through macros, but never
directly.
- Rename log_info_object() to log_object_info(), simply because the
object should be before any other parameters, to follow OO-style
programming style.
This change has two benefits:
- The format string %m will now resolve to the specified error (or to
errno if the specified error is 0. This allows getting rid of a ton of
strerror() invocations, a function that is not thread-safe.
- The specified error can be passed to the journal in the ERRNO= field.
Now of course, we just need somebody to convert all cases of this:
log_error("Something happened: %s", strerror(-r));
into thus:
log_error_errno(-r, "Something happened: %m");
This makes udevadm trigger mirror udevadm info, except that multiple
device names can be specified. Instructions in 60-keyboard.hwdb should
now actually work.
udevadm(8) is updated, but it could use a bit more polishing.

CID#979416. There is no real race here to fix, but lets make coverity
happy and rework the code.
Note that we still fail if the directory is removed _after_ we ran
mkdir(), so the same race is still there. Coverity is complaining, though.
Rewrite the code to make it happy.
(David: rewrote the commit-message to note that this is not a race. If I'm
wrong, blame me, not Ronny!)
In some cases it is preferable to ship system images with a pre-generated
binary hwdb database, to avoid having to build it at runtime, avoid shipping
the source hwdb files, or avoid storing large binary files in /etc.
So if hwdb.bin does not exist in /etc/udev/, fall back to looking for it in
UDEVLIBEXECDIR. This keeps the possibility to add files to /etc/udev/hwdb.d/
and re-generating the database which trumps the one in /usr/lib.
Add a new --usr flag to "udevadm hwdb --update" which puts the database
into UDEVLIBEXECDIR.
Adjust systemd-udev-hwdb-update.service to not generate the file in /etc if we
already have it in /usr.
If a device does not have a major/minor number attached, we use different
database names than if it does. On "change" events, we didn't copy the
devnum over, therefore, we used different paths than on 'add' or 'remove'
events (where devnum was properly copied).
Fix this by always copying the devnum into the udev-device.
(David: added commit-log from email)
Processes expecting static nodes to have the right permissions may order themselves after systemd-udevd.service,
make sure that actually guarantees what is expected.
Once upon a time logging during early boot was unreliable, so extra logging messages were
sent by udev to stderr. That is no longer a concern, so drop all fprintf() calls from udved.
This extends the udev parser to support OP_REMOVE (-=) and adds support
for TAG-= to remove previously set tags. We don't fail if the tag didn't
exist.
This is pretty handy if we ship default rules for seat-assignments and
users want to exclude specific devices from that. They can easily add
rules that drop any automatically added "seat" tags again.
Some kernel modules still take more than one minute to insmod, we no longer rely on the timeout
killing insmod within a given period of time, so just bump this to a much higher value. Its only
purpose is to make sure that nothing stays aronud forever.
Creating the rtnl context is cheap, but freeing it may not be, due to
synchronous close().
Also drop some excessive logging. We now log about the changing ifname
exactly once.
fprintf() does not add new-lines automatically like log_*() does. Add the
missing \n specified so "udevadm" invoked without arguments adds a newline
to:
udevadm: missing or unknown command
Don't exit the name-finding loop when the 'kernel' policy is detected. We should
still find a fallback name if possible in the (very likely) case that no kernel
name is set at all.
Newer kernels export meta-information about the origin of an ifname. Respect this
from the ifname rename logic. We do not rename any interfaces that was originally
named by userspace, nor once which have already been renamed from userspace.
Moreover, we optionally do not (the default) rename interfaces which the kernel
claims to have named in a predictable way.
getopt is usually good at printing out a nice error message when
commandline options are invalid. It distinguishes between an unknown
option and a known option with a missing arg. It is better to let it
do its job and not use opterr=0 unless we actually want to suppress
messages. So remove opterr=0 in the few places where it wasn't really
useful.
When an error in options is encountered, we should not print a lengthy
help() and overwhelm the user, when we know precisely what is wrong
with the commandline. In addition, since help() prints to stdout, it
should not be used except when requested with -h or --help.
Also, simplify things here and there.
This breaks udev-builtin-btrfs.c, which reinvents some of missing.h,
so use missing.h there too.
[zj: removed #include "config.h" and wrapped #include <linux/btrfs.h>
in ifdef HAVE_LINUX_BTRFS_H as discussed on the mailing list.]
We generally have separate man pages for all configuration files.
In this case udev.conf was already described in systemd-udevd.service(8),
but it was hard to find. Docbook makes it hard to add a .so link from
a different section, so describe udev.conf in its own page.
String which ended in an unfinished quote were accepted, potentially
with bad memory accesses.
Reject anything which ends in a unfished quote, or contains
non-whitespace characters right after the closing quote.
_FOREACH_WORD now returns the invalid character in *state. But this return
value is not checked anywhere yet.
Also, make 'word' and 'state' variables const pointers, and rename 'w'
to 'word' in various places. Things are easier to read if the same name
is used consistently.
mbiebl_> am I correct that something like this doesn't work
mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-passwd "Unlock EncFS"'
mbiebl_> systemd seems to strip of the quotes
mbiebl_> systemctl status shows
mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-password Unlock EncFS $RootDir $MountPoint
mbiebl_> which is pretty weird
Some events take longer than the default 30 seconds. Killing those
events will leave the machine halfway configured.
Add a commandline option '--event-timeout' to handle these cases.
MD instantiates devices at open(). This is incomptible with the
locking logic, as the "change" event emitted when stopping a
device will bring it back.
Special care is needed so that we get an error message if the
file failed to parse, but not when it is missing. To avoid duplicating
the same error check in every caller, add an additional 'warn' boolean
to tell config_parse whether a message should be issued.
This makes things both shorter and more robust wrt. to error reporting.
