Lennart Poettering 8e766630f0 tree-wide: drop redundant _cleanup_ macros (#8810)
This drops a good number of type-specific _cleanup_ macros, and patches
all users to just use the generic ones.

In most recent code we abstained from defining type-specific macros, and
this basically removes all those added already, with the exception of
the really low-level ones.

Having explicit macros for this is not too useful, as the expression
without the extra macro is generally just 2ch wider. We should generally
emphesize generic code, unless there are really good reasons for
specific code, hence let's follow this in this case too.

Note that _cleanup_free_ and similar really low-level, libc'ish, Linux
API'ish macros continue to be defined, only the really high-level OO
ones are dropped. From now on this should really be the rule: for really
low-level stuff, such as memory allocation, fd handling and so one, go
ahead and define explicit per-type macros, but for high-level, specific
program code, just use the generic _cleanup_() macro directly, in order
to keep things simple and as readable as possible for the uninitiated.

Note that before this patch some of the APIs (notable libudev ones) were
already used with the high-level macros at some places and with the
generic _cleanup_ macro at others. With this patch we hence unify on the
latter.

Douglas Christman 6c1a6df375 udevadm: prevent segfault in blkid builtin when offset not specified
"--offset" takes an optional argument; if none is specified,
stroull() will attempt to parse a NULL pointer. For example:

$ udevadm test-builtin 'blkid --offset' /sys/dev/block/8:1

Update "--offset" to require an argument; also verify that the
offset is not negative.

Zbigniew Jędrzejewski-Szmek 349cc4a507 build-sys: use #if Y instead of #ifdef Y everywhere
The advantage is that is the name is mispellt, cpp will warn us.

$ git grep -Ee "conf.set\('(HAVE|ENABLE)_" -l|xargs sed -r -i "s/conf.set\('(HAVE|ENABLE)_/conf.set10('\1_/"
$ git grep -Ee '#ifn?def (HAVE|ENABLE)' -l|xargs sed -r -i 's/#ifdef (HAVE|ENABLE)/#if \1/; s/#ifndef (HAVE|ENABLE)/#if ! \1/;'
$ git grep -Ee 'if.*defined\(HAVE' -l|xargs sed -i -r 's/defined\((HAVE_[A-Z0-9_]*)\)/\1/g'
$ git grep -Ee 'if.*defined\(ENABLE' -l|xargs sed -i -r 's/defined\((ENABLE_[A-Z0-9_]*)\)/\1/g'
+ manual changes to meson.build

squash! build-sys: use #if Y instead of #ifdef Y everywhere

v2:
- fix incorrect setting of HAVE_LIBIDN2

Lennart Poettering 1f47f5504c udev: never ask libblkid for detecting superblocks with bad checksums (#6215)
Previously, we'd ask liblkid to also tell us about recognized
superblocks with bad checksums. We'd then log about them and ignore
them. This however created ambuigity problems, see #6110: the
BLKID_SUBLKS_BADCSUM is not as innocent as it appears.

This patch drops bad checksum handling and we ignore all such superblocks
entirely again, as it was the status quo ante
d47f6ca5f9 (where this was snuck in).

Ideally, libblkid would be changed to avoid this ambiguity problems for
bad checksums, but that's not going to happen any time soon, according
to @karelzak.

Fixes: #6110

Nate Clark a1bb2402cb udev-builtin-blkid: Use _cleanup_blkid_free_probe_ to free probe (#6108)

Matt Clarkson 6b5cf3ea62 build-sys: correct blkid.h includes
When using pkg-config to determine the include flags for blkid the
flags are returned as:

    $ pkg-config blkid --cflags
    -I/usr/include/blkid -I/usr/include/uuid

We use the <blkid/blkid.h> include which would be correct when using
the default compiler /usr/include header search path. However, when
cross-compiling the blkid.h will not be installed at /usr/include and
highly likely in a temporary system root. It is futher compounded if
the cross-compile packages are split up and the blkid package is not
available in the same sysroot as the compiler.

Regardless of the compilation setup, the correct include path should be
<blkid.h> if using the pkg-config returned CFLAGS.

Zbigniew Jędrzejewski-Szmek f5e5c28f42 tree-wide: check if errno is greater then zero
gcc is confused by the common idiom of
  return errno ? -errno : -ESOMETHING
and thinks a positive value may be returned. Replace this condition
with errno > 0 to help gcc and avoid many spurious warnings. I filed
a gcc rfe a long time ago, but it hard to say if it will ever be
implemented [1].

Both conventions were used in the codebase, this change makes things
more consistent. This is a follow up to bcb161b023.

Lennart Poettering 07630cea1f util-lib: split our string related calls from util.[ch] into its own file string-util.[ch]
There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.

This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.

Also touches a few unrelated include files.

Kay Sievers 0238d4c660 gpt-auto-generator: apply partition-type flags only to specific partition-types
The partition-type flags are defined independently for every partition-type. Apply
them only to the types where they are defined, and not to the ESP, which does not
appear to share the same set of flags.

Lennart Poettering 329f7803ee udev: automatically create a symlink /dev/disk/by-id/gpt-auto-root if there's a suitable root partition 2014-03-07 03:30:30 +01:00
Lennart Poettering cbd353ce77 udev-builtin-blkid: when we find a GPT partition marked as root disk on the same disk as the ESP, expose a property on the udev device
This is preparation for a logic to automatically discover the root
partition to boot from if no partition has been configured explicitly.

This makes use of our newly defined GPT type GUIDs for our root disks:

 #define GPT_ROOT_X86    SD_ID128_MAKE(44,47,95,40,f2,97,41,b2,9a,f7,d1,31,d5,f0,45,8a)
 #define GPT_ROOT_X86_64 SD_ID128_MAKE(4f,68,bc,e3,e8,cd,4d,b1,96,e7,fb,ca,f9,84,b7,09)

We define differen GUIDs for different architectures to allow images
which finde the right root partition for the appropriate arch.
