Merge branch 'mlx5-packet-credit-fc' into rdma.git
Danit Goldberg says: Packet based credit mode Packet based credit mode is an alternative end-to-end credit mode for QPs set during their creation. Credits are transported from the responder to the requester to optimize the use of its receive resources. In packet-based credit mode, credits are issued on a per packet basis. The advantage of this feature comes while sending large RDMA messages through switches that are short in memory. The first commit exposes QP creation flag and the HCA capability. The second commit adds support for a new DV QP creation flag. The last commit report packet based credit mode capability via the MLX5DV device capabilities. * branch 'mlx5-packet-credit-fc': IB/mlx5: Report packet based credit mode device capability IB/mlx5: Add packet based credit mode support net/mlx5: Expose packet based credit mode Signed-off-by: Jason Gunthorpe <jgg@mellanox.com> |

bpf: Support sk lookup in netns with id 0
David Ahern and Nicolas Dichtel report that the handling of the netns id 0 is incorrect for the BPF socket lookup helpers: rather than finding the netns with id 0, it is resolving to the current netns. This renders the netns_id 0 inaccessible. To fix this, adjust the API for the netns to treat all negative s32 values as a lookup in the current netns (including u64 values which when truncated to s32 become negative), while any values with a positive value in the signed 32-bit integer space would result in a lookup for a socket in the netns corresponding to that id. As before, if the netns with that ID does not exist, no socket will be found. Any netns outside of these ranges will fail to find a corresponding socket, as those values are reserved for future usage.

bpf: fix pointer offsets in context for 32 bit
Currently, pointer offsets in three BPF context structures are broken in two scenarios: i) 32 bit compiled applications running on 64 bit kernels, and ii) LLVM compiled BPF programs running on 32 bit kernels. The latter is due to BPF target machine being strictly 64 bit. So in each of the cases the offsets will mismatch in verifier when checking / rewriting context access. Fix this by providing a helper macro __bpf_md_ptr() that will enforce padding up to 64 bit and proper alignment, and for context access a macro bpf_ctx_range_ptr() which will cover full 64 bit member range on 32 bit archs. For flow_keys, we additionally need to force the size check to sizeof(__u64) as with other pointer types. Fixes: |

RDMA/uverbs: Add missing driver_data
If the struct is used with a driver_udata it should have a trailing driver_data flex array to mark it as having udata. In most cases this forces the end of the struct to be aligned to u64 which is needed to make the trailing driver_data naturally aligned. Unfortunately We have a few cases where the base struct is not aligned to 8 bytes, these are marked with a u32 driver_data and userspace will check for alignment issues when it compiles the driver. Also remove the empty ib_uverbs_modify_qp_resp as nothing uses this. pahole says there is no change to any struct sizes by this change.

media: v4l: fix uapi mpeg slice params definition
We get a headers_check warning about the newly defined ioctl command
structures:
./usr/include/linux/v4l2-controls.h:1105: found __[us]{8,16,32,64} type without #include <linux/types.h>
This is resolved by including linux/types.h, as suggested by the
warning, but there is another problem: Three of the four structures
have an odd number of __u8 headers, but are aligned to 32 bit in the
v4l2_ctrl_mpeg2_slice_params, so we get an implicit padding byte
for each one. To solve that, let's add explicit padding that can
be set to zero and verified in the kernel.

"Provide five new operations in the key_type struct that can be used to
provide access to asymmetric key operations. These will be implemented
for the asymmetric key type in a later patch and may refer to a key
retained in RAM by the kernel or a key retained in crypto hardware.

int (*asym_verify_signature)(struct kernel_pkey_params *params,

Since encrypt, decrypt and sign are identical in their interfaces,
they're rolled together in the asym_eds_op() operation and there's an
operation ID in the params argument to distinguish them.
Verify is different in that we supply the data and the signature
instead and get an error value (or 0) as the only result on the
expectation that this may well be how a hardware crypto device may
work"

RISC-V Patches for the 4.20 Merge Window, Part 2 v2
This tag contains the follow-on patches I'd like to target for the 4.20
merge window. I'm being somewhat conservative here, as while there are
a few patches on the mailing list that were posted early in the merge
window I'd like to let those bake for another round -- this was a fairly
big release as far as RISC-V is concerened, and we need to walk before
we can run.
As far as the patches that made it go:
* A patch to ignore offline CPUs when calculating AT_HWCAP. This should
fix GDB on the HiFive unleashed, which has an embedded core for hart
0 which is exposed to Linux as an offline CPU.
* A move of EM_RISCV to elf-em.h, which is where it should have been to
begin with.
* I've also removed the 64-bit divide routines. I know I'm not really
playing by my own rules here because I posted the patches this
morning, but since they shouldn't be in the kernel I think it's better
to err on the side of going too fast here.
I don't anticipate any more patch sets for the merge window.
Changes since v1:
* Use a consistent base to merge from so the history isn't a mess.

The latest versions of Google camera and codec HAL depends on such feature. At this stage, it supports only stateless codecs. It has been discussed for a long time (at least over the last 3-4 years), and we finally reached to something that seem to work. This series contain both the API and core changes required to support it and a new m2m decoder driver (cedrus). As the current API is still experimental, the only real driver using it (cedrus) was added at staging[1]. We intend to keep it there for a while, in order to test the API. Only when we're sure that this API works for other cases (like encoders), we'll move this driver out of staging and set the API into a stone.

perf tools: Don't clone maps from parent when synthesizing forks
When synthesizing FORK events, we are trying to create thread objects for the already running tasks on the machine. Normally, for a kernel FORK event, we want to clone the parent's maps because that is what the kernel just did. But when synthesizing, this should not be done. If we do, we end up with overlapping maps as we process the sythesized MMAP2 events that get delivered shortly thereafter. Use the FORK event misc flags in an internal way to signal this situation, so we can elide the map clone when appropriate. Signed-off-by: David S. Miller <davem@davemloft.net> Cc: Don Zickus <dzickus@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Joe Mario <jmario@redhat.com> Link: http://lkml.kernel.org/r/20181030.222404.2085088822877051075.davem@davemloft.net [ Added comment about flag use in machine__process_fork_event(), use ternary op in thread__clone_map_groups() as suggested by Jiri ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |

delayacct: track delays from thrashing cache pages
Delay accounting already measures the time a task spends in direct reclaim
and waiting for swapin, but in low memory situations tasks spend can spend
a significant amount of their time waiting on thrashing page cache. This
isn't tracked right now.
To know the full impact of memory contention on an individual task,
measure the delay when waiting for a recently evicted active cache page to
read back into memory.
Also update tools/accounting/getdelays.c:
[hannes@computer accounting]$ sudo ./getdelays -d -p 1
print delayacct stats ON

KEYS: Provide keyctls to drive the new key type ops for asymmetric keys [ver #2]
Provide five keyctl functions that permit userspace to make use of the new
key type ops for accessing and driving asymmetric keys.
(*) Query an asymmetric key.
long keyctl(KEYCTL_PKEY_QUERY,
key_serial_t key, unsigned long reserved,
struct keyctl_pkey_query *info);
Get information about an asymmetric key. The information is returned
in the keyctl_pkey_query struct:
__u32 supported_ops;
A bit mask of flags indicating which ops are supported. This is
constructed from a bitwise-OR of:
KEYCTL_SUPPORTS_{ENCRYPT,DECRYPT,SIGN,VERIFY}
__u32 key_size;
The size in bits of the key.
__u16 max_data_size;
__u16 max_sig_size;
__u16 max_enc_size;
__u16 max_dec_size;
The maximum sizes in bytes of a blob of data to be signed, a signature
blob, a blob to be encrypted and a blob to be decrypted.
reserved must be set to 0. This is intended for future use to hand
over one or more passphrases needed unlock a key.
If successful, 0 is returned. If the key is not an asymmetric key,
EOPNOTSUPP is returned.
(*) Encrypt, decrypt, sign or verify a blob using an asymmetric key.
long keyctl(KEYCTL_PKEY_ENCRYPT,
const struct keyctl_pkey_params *params,
const char *info,
const void *in,
void *out);
long keyctl(KEYCTL_PKEY_DECRYPT,
const struct keyctl_pkey_params *params,
const char *info,
const void *in,
void *out);
long keyctl(KEYCTL_PKEY_SIGN,
const struct keyctl_pkey_params *params,
const char *info,
const void *in,
void *out);
long keyctl(KEYCTL_PKEY_VERIFY,
const struct keyctl_pkey_params *params,
const char *info,
const void *in,
const void *in2);
Use an asymmetric key to perform a public-key cryptographic operation
a blob of data.
The parameter block pointed to by params contains a number of integer
values:
__s32 key_id;
__u32 in_len;
__u32 out_len;
__u32 in2_len;
For a given operation, the in and out buffers are used as follows:
Operation ID in,in_len out,out_len in2,in2_len
======================= =============== =============== ===========
KEYCTL_PKEY_ENCRYPT Raw data Encrypted data -
KEYCTL_PKEY_DECRYPT Encrypted data Raw data -
KEYCTL_PKEY_SIGN Raw data Signature -
KEYCTL_PKEY_VERIFY Raw data - Signature
info is a string of key=value pairs that supply supplementary
information.
The __spare space in the parameter block must be set to 0. This is
intended, amongst other things, to allow the passing of passphrases
required to unlock a key.
If successful, encrypt, decrypt and sign all return the amount of data
written into the output buffer. Verification returns 0 on success.
