Zbigniew Jędrzejewski-Szmek 7dc951ef91 basic/iovec-util: drop IOVEC_NULL 
The macro isn't very useful, we can just use the direct setting to increase
readability.

Zbigniew Jędrzejewski-Szmek 1ca0b482b6 basic/iovec-util: always call the iovec "iovec" 
We were using "i", "iov", and "iovec" in variuos places. Let's be
consistent.

Luca Boccassi 665a3d6d15 systemctl: automatically softreboot/kexec if set up on reboot 
Automatically softreboot if the nextroot has been set up with an OS
tree, or automatically kexec if a kernel has been loaded with kexec
--load.

Add SYSTEMCTL_SKIP_AUTO_KEXEC and SYSTEMCTL_SKIP_AUTO_SOFT_REBOOT to
skip the automated switchover.

Lennart Poettering ea1f38146a io-util: split out iovw_xyz into iovec-wrapper.h 
Let's split these APIs out, they are kinda their own thing.
 2023-10-20 10:43:50 +02:00
Lennart Poettering 986235a99a iovec-util: make IOVEC_INCREMENT a regular function too 
Even more than with the previous commit, this is not a trivial function
and there's no reason to believe this will actually be inlined nor that
it would be beneficial.
 2023-10-20 10:43:50 +02:00
Lennart Poettering 9599ea28b4 iovec-util: make IOVEC_MAKE_STRING() safer 
Let's not accept arbitrary types, but only char* and const char*.
 2023-10-20 10:43:50 +02:00
Lennart Poettering e2a3bb22c8 iovec-util: make IOVEC_NULL const 
compound initialized structs can be placed im immutable memory if const,
hence there's benefit in making this one const too
 2023-10-20 10:43:50 +02:00
Lennart Poettering c24e0dbea1 iovec-util: make IOVEC_TOTAL_SIZE() a regular function 
The function isn't necessarily fast (it's O(n)), and there's no reason
to have it defined as inline function, since it's neither fast, nor
entirely trivial.
 2023-10-20 10:43:50 +02:00
Lennart Poettering bd1ae17833 io-util: split out "struct iovec" related calls into their own .c/.h files 
This is preparation for #28891, which adds a bunch more helpers around
"struct iovec", at which point this really deserves its own .c/.h file.

The idea is that we sooner or later can consider "struct iovec" as an
entirely generic mechanism to reference some binary blob, and is the
go-to type for this purpose whenever we need one.

Lennart Poettering 9bb64f1b8d pidref: make PIDREF_NULL const

Arseny Maslennikov 3677364cc3 basic/missing_syscall: generate defs for fchmodat2(2) 
We will need this to set seccomp filters on this system call regardless
of libseccomp or kernel support.
 2023-10-19 14:07:54 +03:00
Arseny Maslennikov c83f838193 Update system call tables for Linux 6.6 
We are doing this to obtain the definition of fchmodat2.

Just a paranoia.
 2023-10-19 18:31:44 +09:00
Yu Watanabe 2977904cad macro: introduce several helper functions for alignment 
Some of them are not used in this commit, but will be used later.

Yu Watanabe 86cbbc6d05 tree-wide: check if return value of lseek() and friends is negative 
We usually check return value of syscalls or glibc functions by it is
negative or not, something like that `if (stat(path, &st) < 0)`.
Let's also use the same style for lseek() and friends even the type of
their return value is off_t.

Note, fseeko() returns int, instead of off_t.

Lennart Poettering a7a877697f pidref: add new pidref_is_self() helper 
This simply checks if the specified PidRef refers to the process we are
running in.

(In case you wonder why this is not a static inline: to avoid cyclic
header inclusion problems between pidref.h + process-util.h)

Lennart Poettering 3d7ba61a7b pidref: we never have to verify PID 1 
The process exists as long as the kernel/userns exists at all, hence we
don't have to verify a pidfd to it.
