Merge uncontroversial parts of branch 'readlink' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs Pull partial readlink cleanups from Miklos Szeredi. This is the uncontroversial part of the readlink cleanup patch-set that simplifies the default readlink handling. Miklos and Al are still discussing the rest of the series. * git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs: vfs: make generic_readlink() static vfs: remove ".readlink = generic_readlink" assignments vfs: default to generic_readlink() vfs: replace calling i_op->readlink with vfs_readlink() proc/self: use generic_readlink ecryptfs: use vfs_get_link() bad_inode: add missing i_op initializers

The build of sparc allmodconfig fails with the error: "of_irq_to_resource" [drivers/net/ethernet/marvell/mv643xx_eth.ko] undefined! of_irq_to_resource() is defined when CONFIG_OF_IRQ is defined. And also CONFIG_OF_IRQ can only be defined if CONFIG_IRQ is defined. So we can safely use #if defined(CONFIG_OF_IRQ) in the code. Signed-off-by:

Daniel Borkmann says: ==================== Couple of BPF fixes This set contains three BPF fixes for net, one that addresses the complaint from Geert wrt static allocations, and the other is a fix wrt mem accounting that I found recently during testing and there's still one more fix on the map value marking. Thanks! v1 -> v2: - Patch 1 as is. - Fixed kbuild bot issue by letting charging helpers stay in the syscall.c, since there locked_vm is valid and only export the ones needed by bpf_prog_realloc(). Add empty stubs in case the bpf syscall is not enabled. - Added patch 3 that addresses one more issue in map val marking. ==================== Signed-off-by: -

The reason why it wasn't noticed before was, because as mentioned in a08dd0da, mark_map_regs() was doing the id matching incorrectly based on the uncached regs[regno].id. So, in the first loop, we walked all regs and as soon as we found regno == i, then this reg's id was cleared when calling mark_reg_unknown_value() thus that every subsequent register was probed against id of 0 (which, in combination with the PTR_TO_MAP_VALUE_OR_NULL type is an invalid condition that no other register state can hold), and therefore wasn't type transitioned such as in the spilled register case for the second loop. Now since that got fixed, it turned out that 57a09bf0 ("bpf: Detect identical PTR_TO_MAP_VALUE_OR_NULL registers") used mark_reg_unknown_value() incorrectly for the spilled regs, and thus hitting the BUG_ON() in some cases due to regno >= MAX_BPF_REG. Although spilled regs have the same type as the non-spilled regs for the verifier state, that is, struct bpf_reg_state, they are semantically different from the non-spilled regs. In other words, there can be up to 64 (MAX_BPF_STACK / BPF_REG_SIZE) spilled regs in the stack, for example, register R<x> could have been spilled by the program to stack location X, Y, Z, and in mark_map_regs() we need to scan these stack slots of type STACK_SPILL for potential registers that we have to transition from PTR_TO_MAP_VALUE_OR_NULL. Therefore, depending on the location, the spilled_regs regno can be a lot higher than just MAX_BPF_REG's value since we operate on stack instead. The reset in mark_reg_unknown_value() itself is just fine, only that the BUG_ON() was inappropriate for this. Fix it by making a __mark_reg_unknown_value() version that can be called from mark_map_reg() generically; we know for the non-spilled case that the regno is always < MAX_BPF_REG anyway.

Commit aaac3ba9 ("bpf: charge user for creation of BPF maps and programs") made a wrong assumption of charging against prog->pages. Unlike map->pages, prog->pages are still subject to change when we need to expand the program through bpf_prog_realloc(). This can for example happen during verification stage when we need to expand and rewrite parts of the program. Should the required space cross a page boundary, then prog->pages is not the same anymore as its original value that we used to bpf_prog_charge_memlock() on. Thus, we'll hit a wrap-around during bpf_prog_uncharge_memlock() when prog is freed eventually. I noticed this that despite having unlimited memlock, programs suddenly refused to load with EPERM error due to insufficient memlock. There are two ways to fix this issue. One would be to add a cached variable to struct bpf_prog that takes a snapshot of prog->pages at the time of charging. The other approach is to also account for resizes. I chose to go with the latter for a couple of reasons: i) We want accounting rather to be more accurate instead of further fooling limits, ii) adding yet another page counter on struct bpf_prog would also be a waste just for this purpose. We also do want to charge as early as possible to avoid going into the verifier just to find out later on that we crossed limits. The only place that needs to be fixed is bpf_prog_realloc(), since only here we expand the program, so we try to account for the needed delta and should we fail, call-sites check for outcome anyway. On cBPF to eBPF migrations, we don't grab a reference to the user as they are charged differently. With that in place, my test case worked fine.

Geert rightfully complained that 7bd509e3 ("bpf: add prog_digest and expose it via fdinfo/netlink") added a too large allocation of variable 'raw' from bss section, and should instead be done dynamically: # ./scripts/bloat-o-meter kernel/bpf/core.o.1 kernel/bpf/core.o.2 add/remove: 3/0 grow/shrink: 0/0 up/down: 33291/0 (33291) function old new delta raw - 32832 +32832 [...] Since this is only relevant during program creation path, which can be considered slow-path anyway, lets allocate that dynamically and be not implicitly dependent on verifier mutex. Move bpf_prog_calc_digest() at the beginning of replace_map_fd_with_map_ptr() and also error handling stays straight forward. Reported-by:

Pablo Neira Ayuso says: ==================== GTP tunneling fixes for net The following patchset contains two GTP tunneling fixes for your net tree, they are: 1) Offset to IPv4 header in gtp_check_src_ms_ipv4() is incorrect, thus this function always succeeds and therefore this defeats this sanity check. This allows packets that have no PDP to go though, patch from Lionel Gauthier. 2) According to Note 0 of Figure 2 in Section 6 of 3GPP TS 29.060 v13.5.0 Release 13, always set GTPv1 reserved bit to zero. This may cause interoperability problems, patch from Harald Welte. Please, apply, thanks a lot! ==================== Signed-off-by: -

When generating a GTPv1 header in gtp1_push_header(), initialize the 'reserved' bit to zero. All 3GPP specifications for GTPv1 from Release 99 through Release 13 agree that a transmitter shall set this bit to zero, see e.g. Note 0 of Figure 2 in Section 6 of 3GPP TS 29.060 v13.5.0 Release 13, available from http://www.etsi.org/deliver/etsi_ts/129000_129099/129060/13.05.00_60/ts_129060v130500p.pdfSigned-off-by:
