2024-01-22exec: Fix error handling in begin_new_exec()Bernd Edlinger1-0/+3
If get_unused_fd_flags() fails, the error handling is incomplete because bprm->cred is already set to NULL, and therefore free_bprm will not unlock the cred_guard_mutex. Note there are two error conditions which end up here, one before and one after bprm->cred is cleared.

2024-01-22perf dwarf-aux: Check allowed DWARF OpsNamhyung Kim1-4/+40
The DWARF location expression can be fairly complex and it'd be hard to match it with the condition correctly. So let's be conservative and only allow simple expressions. For now it just checks the first operation in the list. The following operations looks ok: * DW_OP_stack_value * DW_OP_deref_size * DW_OP_deref * DW_OP_piece To refuse complex (and unsupported) location expressions, add check_allowed_ops() to compare the rest of the list. It seems earlier result contained those unsupported expressions. For example, I found some local struct variable is placed like below. <2><43d1517>: Abbrev Number: 62 (DW_TAG_variable) <43d1518> DW_AT_location : 15 byte block: 91 50 93 8 91 78 93 4 93 84 8 91 68 93 4 (DW_OP_fbreg: -48; DW_OP_piece: 8; DW_OP_fbreg: -8; DW_OP_piece: 4; DW_OP_piece: 1028; DW_OP_fbreg: -24; DW_OP_piece: 4) Another example is something like this. 0057c8be ffffffffffffffff ffffffff812109f0 (base address) 0057c8ce ffffffff812112b5 ffffffff812112c8 (DW_OP_breg3 (rbx): 0; DW_OP_constu: 18446744073709551612; DW_OP_and; DW_OP_stack_value) It should refuse them.

2024-01-22perf annotate-data: Support stack variablesNamhyung Kim3-24/+93
Local variables are allocated in the stack and the location list should look like base register(s) and an offset. Extend the die_find_variable_by_reg() to handle the following expressions * DW_OP_breg{0..31} * DW_OP_bregx * DW_OP_fbreg Ususally DWARF subprogram entries have frame base information and use it to locate stack variable like below: <2><43d1575>: Abbrev Number: 62 (DW_TAG_variable) <43d1576> DW_AT_location : 2 byte block: 91 7c (DW_OP_fbreg: -4) <--- here <43d1579> DW_AT_name : (indirect string, offset: 0x2c00c9): i <43d157d> DW_AT_decl_file : 1 <43d157e> DW_AT_decl_line : 78 <43d157f> DW_AT_type : <0x43d19d7> I found some differences on saving the frame base between gcc and clang. The gcc uses the CFA to get the base so it needs to check the current frame's CFI info.

Factor out match_var_offset() to check global and local variables in the same way.

2024-01-22perf annotate-data: Support global variablesNamhyung Kim4-13/+92
Global variables are accessed using PC-relative address so it needs to be handled separately. The PC-rel addressing is detected by using DWARF_REG_PC. On x86, %rip register would be used. The address can be calculated using the ip and offset in the instruction. But it should start from the next instruction so add calculate_pcrel_addr() to do it properly. But global variables defined in a different file would only have a declaration which doesn't include a location list. So it first tries to get the type info using the address, and then looks up the variable declarations using name. The name of global variables should be get from the symbol table. The declaration would have the type info. So extend find_var_type() to take both address and name for global variables. The stat is now looks like: Annotate data type stats: total 294, ok 153 (52.0%), bad 141 (48.0%) ----------------------------------------------------------- 30 : no_sym 32 : no_mem_ops 61 : no_var 10 : no_typeinfo 8 : bad_offset Reviewed-by: Ian Rogers <irogers@google.com> Cc: Stephane Eranian <eranian@google.com> Cc: Masami Hiramatsu <mhiramat@kernel.org> Link: https://lore.kernel.org/r/20240117062657.985479-7-namhyung@kernel.org Signed-off-by: Namhyung Kim <namhyung@kernel.org>
2024-01-22perf annotate-data: Handle PC-relative addressingNamhyung Kim1-18/+38
Extend find_data_type_die() to find data type from PC-relative address using die_find_variable_by_addr(). Users need to pass the address for the (global) variable. The offset for the variable should be updated after finding the type because the offset in the instruction is just to calcuate the address for the variable. So it changed to pass a pointer to offset and renamed it to 'poffset'. First it searches variables in the CU DIE as it's likely that the global variables are defined in the file level. And then it iterates the scope DIEs to find a local (static) variable.

2024-01-22perf annotate-data: Add stack operation pseudo typeNamhyung Kim2-0/+27
A typical function prologue and epilogue include multiple stack operations to save and restore the current value of registers. On x86, it looks like below: push r15 push r14 push r13 push r12 ... pop r12 pop r13 pop r14 pop r15 ret As these all touches the stack memory region, chances are high that they appear in a memory profile data. But these are not used for any real purpose yet so it'd return no types. One of my profile type shows that non neglible portion of data came from the stack operations. It also seems GCC generates more stack operations than clang.

On x86, instructions for array access often looks like below. mov 0x1234(%rax,%rbx,8), %rcx Usually the first register holds the type information and the second one has the index. And the current code only looks up a variable for the first register. But it's possible to be in the other way around so it needs to check the second register if the first one failed.

2024-01-22net/rds: Fix UBSAN: array-index-out-of-bounds in rds_cmsg_recvSharath Srinivasan1-1/+1
Syzcaller UBSAN crash occurs in rds_cmsg_recv(), which reads inc->i_rx_lat_trace[j + 1] with index 4 (3 + 1), but with array size of 4 (RDS_RX_MAX_TRACES). Here 'j' is assigned from rs->rs_rx_trace[i] and in-turn from trace.rx_trace_pos[i] in rds_recv_track_latency(), with both arrays sized 3 (RDS_MSG_RX_DGRAM_TRACE_MAX).

2024-01-22net: micrel: Fix PTP frame parsing for lan8814Horatiu Vultur1-0/+11
The HW has the capability to check each frame if it is a PTP frame, which domain it is, which ptp frame type it is, different ip address in the frame. And if one of these checks fail then the frame is not timestamp. Most of these checks were disabled except checking the field minorVersionPTP inside the PTP header. Meaning that once a partner sends a frame compliant to 8021AS which has minorVersionPTP set to 1, then the frame was not timestamp because the HW expected by default a value of 0 in minorVersionPTP. This is exactly the same issue as on lan8841. Fix this issue by removing this check so the userspace can decide on this.

2024-01-22dpll: fix register pin with unregistered parent pinArkadiusz Kubalewski1-6/+0
In case of multiple kernel module instances using the same dpll device: if only one registers dpll device, then only that one can register directly connected pins with a dpll device. When unregistered parent is responsible for determining if the muxed pin can be registered with it or not, the drivers need to be loaded in serialized order to work correctly - first the driver instance which registers the direct pins needs to be loaded, then the other instances could register muxed type pins. Allow registration of a pin with a parent even if the parent was not yet registered, thus allow ability for unserialized driver instance load order. Do not WARN_ON notification for unregistered pin, which can be invoked for described case, instead just return error.

If parent pin was unregistered but child pin was not, the userspace would see the "zombie" pins - the ones that were registered with a parent pin (dpll_pin_on_pin_register(..)). Technically those are not available - as there is no dpll device in the system. Do not dump those pins and prevent userspace from any interaction with them. Provide a unified function to determine if the pin is available and use it before acting/responding for user requests.

2024-01-22dpll: fix pin dump crash for rebound moduleArkadiusz Kubalewski3-18/+69
When a kernel module is unbound but the pin resources were not entirely freed (other kernel module instance of the same PCI device have had kept the reference to that pin), and kernel module is again bound, the pin properties would not be updated (the properties are only assigned when memory for the pin is allocated), prop pointer still points to the kernel module memory of the kernel module which was deallocated on the unbind. If the pin dump is invoked in this state, the result is a kernel crash. Prevent the crash by storing persistent pin properties in dpll subsystem, copy the content from the kernel module when pin is allocated, instead of using memory of the kernel module.

When wake_lock_waiters() is called to handle an error, requests on the acquiring list are failed with that error and no flushing takes place. Briefly moving them to the running list is not only pointless but also harmful: if exclusive lock gets acquired before all of their state machines are scheduled and go through rbd_lock_del_request(), we trigger rbd_assert(list_empty(&rbd_dev->running_list)); in rbd_try_acquire_lock().
