allow sleep in qed_mcp_trace_dump()","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nqed: allow sleep in qed_mcp_trace_dump()\n\nBy default, qed_mcp_cmd_and_union() delays 10us at a time in a loop\nthat can run 500K times, so calls to qed_mcp_nvm_rd_cmd()\nmay block the current thread for over 5s.\nWe observed thread scheduling delays over 700ms in production,\nwith stacktraces pointing to this code as the culprit.\n\nqed_mcp_trace_dump() is called from ethtool, so sleeping is permitted.\nIt already can sleep in qed_mcp_halt(), which calls qed_mcp_cmd().\nAdd a \"can sleep\" parameter to qed_find_nvram_image() and\nqed_nvram_read() so they can sleep during qed_mcp_trace_dump().\nqed_mcp_trace_get_meta_info() and qed_mcp_trace_read_meta(),\ncalled only by qed_mcp_trace_dump(), allow these functions to sleep.\nI can't tell if the other caller (qed_grc_dump_mcp_hw_dump()) can sleep,\nso keep b_can_sleep set to false when it calls these functions.\n\nAn example stacktrace from a custom warning we added to the kernel\nshowing a thread that has not scheduled despite long needing resched:\n[ 2745.362925,17]

been resolved:\n\nqed: allow sleep in qed_mcp_trace_dump()\n\nBy default, qed_mcp_cmd_and_union() delays 10us at a time in a loop\nthat can run 500K times, so calls to qed_mcp_nvm_rd_cmd()\nmay block the current thread for over 5s.\nWe observed thread scheduling delays over 700ms in production,\nwith stacktraces pointing to this code as the culprit.\n\nqed_mcp_trace_dump() is called from ethtool, so sleeping is permitted.\nIt already can sleep in qed_mcp_halt(), which calls qed_mcp_cmd().\nAdd a \"can sleep\" parameter to qed_find_nvram_image() and\nqed_nvram_read() so they can sleep during qed_mcp_trace_dump().\nqed_mcp_trace_get_meta_info() and qed_mcp_trace_read_meta(),\ncalled only by qed_mcp_trace_dump(), allow these functions to sleep.\nI can't tell if the other caller (qed_grc_dump_mcp_hw_dump()) can sleep,\nso keep b_can_sleep set to false when it calls these functions.\n\nAn example stacktrace from a custom warning we added to the kernel\nshowing a thread that has not scheduled despite long needing resched:\n[ 2745.362925,17] ------------[ cut here ]------------\n[ 2745.362941,17] WARNING: CPU: 23 PID: 5640 at arch/x86/kernel/irq.c:233
