2021-08-26perf/x86/intel/uncore: Fix integer overflow on 23 bit left shift of a u32Colin Ian King
The u32 variable pci_dword is being masked with 0x1fffffff and then left shifted 23 places. The shift is a u32 operation,so a value of 0x200 or more in pci_dword will overflow the u32 and only the bottow 32 bits are assigned to addr. I don't believe this was the original intent. Fix this by casting pci_dword to a resource_size_t to ensure no overflow occurs. Note that the mask and 12 bit left shift operation does not need this because the mask SNR_IMC_MMIO_MEM0_MASK and shift is always a 32 bit value.

2021-08-25Merge branch 'bpf: tcp: Allow bpf-tcp-cc to call bpf_(get|set)sockopt'Alexei Starovoitov
Martin KaFai says: ==================== This set allows the bpf-tcp-cc to call bpf_setsockopt. One use case is to allow a bpf-tcp-cc switching to another cc during init(). For example, when the tcp flow is not ecn ready, the bpf_dctcp can switch to another cc by calling setsockopt(TCP_CONGESTION). bpf_getsockopt() is also added to have a symmetrical API, so less usage surprise. v2: - Not allow switching to kernel's tcp_cdg because it is the only kernel tcp-cc that stores a pointer to icsk_ca_priv. Please see the commit log in patch 1 for details. Test is added in patch 4 to check switching to tcp_cdg. - Refactor the logic finding the offset of a func ptr in the "struct tcp_congestion_ops" to prog_ops_moff() in patch 1. - bpf_setsockopt() has been disabled in release() since v1 (please see commit log in patch 1 for reason). bpf_getsockopt() is also disabled together in release() in v2 to avoid usage surprise because both of them are usually expected to be available together. bpf-tcp-cc can already use PTR_TO_BTF_ID to read from tcp_sock. ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>

This patch adds a new "struct network_helper_opts" for the future option needs. It starts with the "cc" and "timeout_ms" option.

2021-08-25bpf: tcp: Allow bpf-tcp-cc to call bpf_(get|set)sockoptMartin KaFai Lau
This patch allows the bpf-tcp-cc to call bpf_setsockopt. One use case is to allow a bpf-tcp-cc switching to another cc during init(). For example, when the tcp flow is not ecn ready, the bpf_dctcp can switch to another cc by calling setsockopt(TCP_CONGESTION). During setsockopt(TCP_CONGESTION), the new tcp-cc's init() will be called and this could cause a recursion but it is stopped by the current trampoline's logic (in the prog->active counter). While retiring a bpf-tcp-cc (e.g. in tcp_v[46]_destroy_sock()), the tcp stack calls bpf-tcp-cc's release(). To avoid the retiring bpf-tcp-cc making further changes to the sk, bpf_setsockopt is not available to the bpf-tcp-cc's release(). This will avoid release() making setsockopt() call that will potentially allocate new resources. Although the bpf-tcp-cc already has a more powerful way to read tcp_sock from the PTR_TO_BTF_ID, it is usually expected that bpf_getsockopt and bpf_setsockopt are available together. Thus, bpf_getsockopt() is also added to all tcp_congestion_ops except release(). When the old bpf-tcp-cc is calling setsockopt(TCP_CONGESTION) to switch to a new cc, the old bpf-tcp-cc will be released by bpf_struct_ops_put(). Thus, this patch also puts the bpf_struct_ops_map after a rcu grace period because the trampoline's image cannot be freed while the old bpf-tcp-cc is still running. bpf-tcp-cc can only access icsk_ca_priv as SCALAR. All kernel's tcp-cc is also accessing the icsk_ca_priv as SCALAR. The size of icsk_ca_priv has already been raised a few times to avoid extra kmalloc and memory referencing. The only exception is the kernel's tcp_cdg.c that stores a kmalloc()-ed pointer in icsk_ca_priv. To avoid the old bpf-tcp-cc accidentally overriding this tcp_cdg's pointer value stored in icsk_ca_priv after switching and without over-complicating the bpf's verifier for this one exception in tcp_cdg, this patch does not allow switching to tcp_cdg. If there is a need, bpf_tcp_cdg can be implemented and then use the bpf_sk_storage as the extended storage. bpf_sk_setsockopt proto has only been recently added and used in bpf-sockopt and bpf-iter-tcp, so impose the tcp_cdg limitation in the same proto instead of adding a new proto specifically for bpf-tcp-cc.

2021-08-25cifs: fork arc4 and create a separate module for it for cifs and other usersRonnie Sahlberg
We can not drop ARC4 and basically destroy CIFS connectivity for almost all CIFS users so create a new forked ARC4 module that CIFS and other subsystems that have a hard dependency on ARC4 can use.

2021-08-25cifs: enable fscache usage even for files opened as rwShyam Prasad N
So far, the fscache implementation we had supports only a small set of use cases. Particularly for files opened with O_RDONLY. This commit enables it even for rw based file opens. It also enables the reuse of cached data in case of mount option (cache=singleclient) where it is guaranteed that this is the only client (and server) which operates on the files. There's also a single line change in fscache.c to get around a bug seen in fscache.

2021-08-25cifs: fix wrong release in sess_alloc_buffer() failed pathDing Hui
smb_buf is allocated by small_smb_init_no_tc(), and buf type is CIFS_SMALL_BUFFER, so we should use cifs_small_buf_release() to release it in failed path.
