Implement the necessary software segmentation on the normal
TX path so that fast-xmit can use segmentation offload if
the hardware (or driver) supports it.
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
If drivers want to support S/G (really just gather DMA on TX) then
we can now easily support this on the fast-xmit path since it just
needs to write to the ethernet header (and already has a check for
that being possible.)
However, disallow this on the regular TX path (which has to handle
fragmentation, software crypto, etc.) by calling skb_linearize().
Also allow the related HIGHDMA since that's not interesting to the
code in mac80211 at all anyway.
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
When we go through the complete TX processing, there are a number
of things like fragmentation and software crypto that require the
checksum to be calculated already.
In favour of maintainability, instead of adding the necessary call
to skb_checksum_help() in all the places that need it, just do it
once before the regular TX processing.
Right now this only affects the TI wlcore and QCA ath10k drivers
since they're the only ones using checksum offload. The previous
commits enabled fast-xmit for them in almost all cases.
For wlcore this even fixes a corner case: when a key fails to be
programmed to hardware software encryption gets used, encrypting
frames with a bad checksum.

For hwsim, the duration field in frames is already not valid for
the common case of HT/VHT MCSes, so there's little point in trying
to keep it accurate for the legacy rates. Enable the fast-xmit code
to allow testing that, although given the dependency on hardware
crypto it will only be enabled in open network configurations.

In order to speed up mac80211's TX path, add the "fast-xmit" cache
that will cache the data frame 802.11 header and other data to be

external triggers imply changes, but a lot of the checks done per

WARNING: vmlinux.o(.text.unlikely+0x3864): Section mismatch in
reference from the function cpumask_empty.constprop.3() to the
variable .init.data:nmi_ipi_mask
which comes from the cpumask_empty usage in arch/x86/kernel/nmi_selftest.c.
Normally we would not see a symbol entry for cpumask_empty since it is:
static inline bool cpumask_empty(const struct cpumask *srcp)
however in this case, the variant of the symbol gets emitted when GCC does
constant propagation optimization.

As Guenter pointed out, we were never really calculating the extable entry
size because the pointer arithmetic was simply wrong. We want to check
we're handling the second relocation in __ex_table to infer an entry size,
but we were using (void*) pointers instead of Elf_Rel[a]* ones.
This fixes the problem by moving that check in the caller (since we can
deal with different types of relocations) and add is_second_extable_reloc()
to make the whole thing more readable.

Signed-off-by: Vinod Koul <vinod.koul@intel.com>
Recently Andy changed the 64-bit syscall logic so that
pt_regs->ax is initially set to -ENOSYS, and on syscall exit,
it is updated with the actual return value. This simplified
the logic there.
This patch does the same for 32-bit syscall entry points.
The check for %rax being too big is moved to be just before
the call instruction which dispatches execution through the
syscall table.
There is no way to accidentally skip this check now by jumping
to a label after it. This allows us to remove redundant checks
after ptrace et al.
If %rax is too big, we just skip over the (call, write %rax to
pt_regs->ax) instruction pair. pt_regs->ax remains set to -ENOSYS,
and it gets returned to userspace.
Similar to 64-bit code, this eliminates the "ia32_badsys" code path.
Run-tested.

This change makes the check exact (no more false positives
on "negative" addresses).
Andy explains:
"Canonical addresses either start with 17 zeros or 17 ones.
In the old code, we checked that the top (64-47) = 17 bits were all
zero. We did this by shifting right by 47 bits and making sure that
nothing was left.
In the new code, we're shifting left by (64 - 48) = 16 bits and then
signed shifting right by the same amount, this propagating the 17th
highest bit to all positions to its left. If we get the same value we
started with, then we're good to go."
While it isn't really important to be fully correct here -
almost all addresses we'll ever see will be userspace ones,
but OTOH it looks to be cheap enough: the new code uses
two more ALU ops but preserves %rcx, allowing to not
reload it from pt_regs->cx again.
On disassembly level, the changes are:
cmp %rcx,0x80(%rsp) -> mov 0x80(%rsp),%r11; cmp %rcx,%r11
shr $0x2f,%rcx -> shl $0x10,%rcx; sar $0x10,%rcx; cmp %rcx,%r11
mov 0x58(%rsp),%rcx -> (eliminated)

During some code analysis I realized that atomic_add(), atomic_sub()

is defined multiple times:
atomic_inc: 544 duplicates
atomic_dec: 215 duplicates
atomic_dec_and_test: 107 duplicates
atomic64_inc: 38 duplicates
[...]
Each definition is exact equally, e.g.:
ffffffff813171b8 <atomic_add>:
55 push %rbp
48 89 e5 mov %rsp,%rbp
f0 01 3e lock add %edi,(%rsi)
5d pop %rbp
c3 retq
In turn each definition has one or more callsites (sure):
ffffffff81317c78: e8 3b f5 ff ff callq ffffffff813171b8 <atomic_add> [...]
ffffffff8131a062: e8 51 d1 ff ff callq ffffffff813171b8 <atomic_add> [...]
ffffffff8131a190: e8 23 d0 ff ff callq ffffffff813171b8 <atomic_add> [...]
The other way around would be to remove the static linkage - but
I prefer an enforced inlining here.
Before:
text data bss dec hex filename
81467393 19874720 20168704 121510817 73e1ba1 vmlinux.orig
After:
text data bss dec hex filename
81461323 19874720 20168704 121504747 73e03eb vmlinux.inlined
Yes, the inlining here makes the kernel even smaller! ;)
Linus further observed:
"I have this memory of having seen that before - the size
heuristics for gcc getting confused by inlining.
[...]
It might be a good idea to mark things that are basically just
wrappers around a single (or a couple of) asm instruction to be
always_inline."

.config files that do not have MFD_SYSCON set.
Omaps now have a dependency to MFD_SYSCON for system control
module generic register area and some clocks with the changes
done in omap-for-v4.1/prcm-dts branch.
This can be pulled on top of omap-for-v4.1/prcm-dts, or into
fixes for v4.1.
We already do have a slight MFD_SYSCON dependency for
REGULATOR_PBIAS for dual voltage MMC cards on the first MMC
bus for many devices, so from that point of view this can
also be merged separately from omap-for-v4.1/prcm-dts.

If we allocate a seed on behalf ot the user in crypto_rng_reset,
we must ensure that it is zeroed afterwards or the RNG may be
compromised.

Now that crypto_rng_reset takes a const argument, we no longer
need to cast away the const qualifier.

Now that all rng implementations have switched over to the new
interface, we can remove the old low-level interface.

The file internal.h is only meant to be used by internel API
implementation and not algorithm implementations. In fact it
isn't even needed here so this patch removes it.

This patch converts the DRBG implementation to the new low-level

This allows us to get rid of struct drbg_gen by using the new RNG
API instead.
