Commit 910cd32e55 ("parisc: Fix and enable seccomp filter support")
introduced a regression in ptrace-based syscall tampering: when tracer
changes syscall number to -1, the kernel fails to initialize %r28 with
-ENOSYS and subsequently fails to return the error code of the failed
syscall to userspace.
This erroneous behaviour could be observed with a simple strace syscall
fault injection command which is expected to print something like this:
$ strace -a0 -ewrite -einject=write:error=enospc echo hello
write(1, "hello\n", 6) = -1 ENOSPC (No space left on device) (INJECTED)
write(2, "echo: ", 6) = -1 ENOSPC (No space left on device) (INJECTED)
write(2, "write error", 11) = -1 ENOSPC (No space left on device) (INJECTED)
write(2, "\n", 1) = -1 ENOSPC (No space left on device) (INJECTED)
+++ exited with 1 +++
After commit 910cd32e55 it loops printing
something like this instead:
write(1, "hello\n", 6../strace: Failed to tamper with process 12345: unexpectedly got no error (return value 0, error 0)
) = 0 (INJECTED)
This bug was found by strace test suite.

Commit 8099b047ec ("exec: load_script: don't blindly truncate

truncated interpreter path. However, it was overeager and also refused
to truncate arguments as well, which broke userspace, and it was
reverted. This attempts the protection again, but allows arguments to
remain truncated. In an effort to improve readability, helper functions
and comments have been added.

====================
Address recent issues found in netdev page_frag_alloc usage
This patch set addresses a couple of issues that I had pointed out to Jann
Horn in response to a recent patch submission.
The first issue is that I wanted to avoid the need to read/modify/write the
size value in order to generate the value for pagecnt_bias. Instead we can
just use a fixed constant which reduces the need for memory read operations
and the overall number of instructions to update the pagecnt bias values.
The other, and more important issue is, that apparently we were letting tun
access the napi_alloc_cache indirectly through netdev_alloc_frag and as a
result letting it create unaligned accesses via unaligned allocations. In
order to prevent this I have added a call to SKB_DATA_ALIGN for the fragsz
field so that we will keep the offset in the napi_alloc_cache
SMP_CACHE_BYTES aligned.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
This patch addresses the fact that there are drivers, specifically tun,
that will call into the network page fragment allocators with buffer sizes
that are not cache aligned. Doing this could result in data alignment
and DMA performance issues as these fragment pools are also shared with the
skb allocator and any other devices that will use napi_alloc_frags or
netdev_alloc_frags.

This patch replaces the size + 1 value introduced with the recent fix for 1
byte allocs with a constant value.
The idea here is to reduce code overhead as the previous logic would have
to read size into a register, then increment it, and write it back to
whatever field was being used. By using a constant we can avoid those
memory reads and arithmetic operations in favor of just encoding the
maximum value into the operation itself.

The function-local variable "delay" enters the loop interpreted as delay
in bits. However, inside the loop it gets overwritten by the result of
mlxsw_sp_pg_buf_delay_get(), and thus leaves the loop as quantity in
cells. Thus on second and further loop iterations, the headroom for a
given priority is configured with a wrong size.
Fix by introducing a loop-local variable, delay_cells. Rename thres to
thres_cells for consistency.
