Subject: [PATCH 14/15] arch: add split IPC system calls where needed
Date: Thu, 10 Jan 2019 16:24:34 +0000 [thread overview]
Message-ID: <20190110162435.309262-15-arnd@arndb.de> (raw)
In-Reply-To: <20190110162435.309262-1-arnd@arndb.de>
The IPC system call handling is highly inconsistent across architectures,
some use sys_ipc, some use separate calls, and some use both. We also
have some architectures that require passing IPC_64 in the flags, and
others that set it implicitly.
For the additon of a y2083 safe semtimedop() system call, I chose to only
support the separate entry points, but that requires first supporting
the regular ones with their own syscall numbers.
The IPC_64 is now implied by the new semctl/shmctl/msgctl system
calls even on the architectures that require passing it with the ipc()
multiplexer.
I'm not adding the new semtimedop() or semop() on 32-bit architectures,
those will get implemented using the new semtimedop_time64() version
that gets added along with the other time64 calls.
Three 64-bit architectures (powerpc, s390 and sparc) get semtimedop().

One aspect here that might be a bit controversial is the use of
the same system call numbers across all architectures, synchronizing
all of them with the x86-32 numbers. With the new syscall.tbl
files, I hope we can just keep doing that in the future, and no
longer require the architecture maintainers to assign a number.
This is mainly useful for implementers of the C libraries: if
we can add future system calls everywhere at the same time, using
a particular version of the kernel headers also guarantees that
the system call number macro is visible.

Subject: [PATCH 14/15] arch: add split IPC system calls where needed
Date: Thu, 10 Jan 2019 17:24:34 +0100 [thread overview]
Message-ID: <20190110162435.309262-15-arnd@arndb.de> (raw)
In-Reply-To: <20190110162435.309262-1-arnd@arndb.de>
The IPC system call handling is highly inconsistent across architectures,
some use sys_ipc, some use separate calls, and some use both. We also
have some architectures that require passing IPC_64 in the flags, and
others that set it implicitly.
For the additon of a y2083 safe semtimedop() system call, I chose to only
support the separate entry points, but that requires first supporting
the regular ones with their own syscall numbers.
The IPC_64 is now implied by the new semctl/shmctl/msgctl system
calls even on the architectures that require passing it with the ipc()
multiplexer.
I'm not adding the new semtimedop() or semop() on 32-bit architectures,
those will get implemented using the new semtimedop_time64() version
that gets added along with the other time64 calls.
Three 64-bit architectures (powerpc, s390 and sparc) get semtimedop().

One aspect here that might be a bit controversial is the use of
the same system call numbers across all architectures, synchronizing
all of them with the x86-32 numbers. With the new syscall.tbl
files, I hope we can just keep doing that in the future, and no
longer require the architecture maintainers to assign a number.
This is mainly useful for implementers of the C libraries: if
we can add future system calls everywhere at the same time, using
a particular version of the kernel headers also guarantees that
the system call number macro is visible.

have some architectures that require passing IPC_64 in the flags, and
others that set it implicitly.
For the additon of a y2083 safe semtimedop() system call, I chose to only
support the separate entry points, but that requires first supporting
the regular ones with their own syscall numbers.
The IPC_64 is now implied by the new semctl/shmctl/msgctl system
calls even on the architectures that require passing it with the ipc()
multiplexer.
I'm not adding the new semtimedop() or semop() on 32-bit architectures,
those will get implemented using the new semtimedop_time64() version
that gets added along with the other time64 calls.
Three 64-bit architectures (powerpc, s390 and sparc) get semtimedop().

One aspect here that might be a bit controversial is the use of
the same system call numbers across all architectures, synchronizing
all of them with the x86-32 numbers. With the new syscall.tbl
files, I hope we can just keep doing that in the future, and no
longer require the architecture maintainers to assign a number.
This is mainly useful for implementers of the C libraries: if
we can add future system calls everywhere at the same time, using
a particular version of the kernel headers also guarantees that
the system call number macro is visible.
