[PATCH 3/5] Drivers: hv: kvp: Fix the recent regression caused by incorrect clean-up

by kys＠linuxonhyperv.com

From: Dexuan Cui <decui(a)microsoft.com> In kvp_send_key(), we do need call process_ib_ipinfo() if message->kvp_hdr.operation is KVP_OP_GET_IP_INFO, because it turns out the userland hv_kvp_daemon needs the info of operation, adapter_id and addr_family. With the incorrect fc62c3b1977d, the host can't get the VM's IP via KVP. And, fc62c3b1977d added a "break;", but actually forgot to initialize the key_size/value in the case of KVP_OP_SET, so the default key_size of 0 is passed to the kvp daemon, and the pool files /var/lib/hyperv/.kvp_pool_* can't be updated. This patch effectively rolls back the previous fc62c3b1977d, and correctly fixes the "this statement may fall through" warnings. This patch is tested on WS 2012 R2 and 2016.

[PATCH v2] x86/microcode: Handle negative microcode revisions

by Andi Kleen

From: Andi Kleen <ak(a)linux.intel.com> The Intel microcode revision space is unsigned. Inside Intel there are special microcodes that have the highest bit set, and they are considered to have a higher revision than any microcodes that don't have this bit set. The function comparing the microcode revision in the Linux driver compares u32 with int, which ends up being signed extended to long on 64bit systems. This results in these highest bit set microcode revision not loading because their revision appears negative and smaller than the existing microcode. Change the comparison to unsigned. With that the loading works as expected.

[PATCH 2/3] tracing: Fix synthetic event to allow semicolon at end

by Steven Rostedt

From: Masami Hiramatsu <mhiramat(a)kernel.org> Fix synthetic event to allow independent semicolon at end. The synthetic_events interface accepts a semicolon after the last word if there is no space. # echo "myevent u64 var;" >> synthetic_events But if there is a space, it returns an error. # echo "myevent u64 var ;" > synthetic_events sh: write error: Invalid argument This behavior is difficult for users to understand.

[PATCH 1/3] tracing: Fix synthetic event to accept unsigned modifier

by Steven Rostedt

From: Masami Hiramatsu <mhiramat(a)kernel.org> Fix synthetic event to accept unsigned modifier for its field type correctly. Currently, synthetic_events interface returns error for "unsigned" modifiers as below; # echo "myevent unsigned long var" >> synthetic_events sh: write error: Invalid argument This is because argv_split() breaks "unsigned long" into "unsigned" and "long", but parse_synth_field() doesn't expected it. With this fix, synthetic_events can handle the "unsigned long" correctly like as below; # echo "myevent unsigned long var" >> synthetic_events # cat synthetic_events myevent unsigned long var Link: http://lkml.kernel.org/r/153986832571.18251.8448135724590496531.stgit@devbox Cc: Shuah Khan <shuah(a)kernel.org> Cc: Tom Zanussi <tom.zanussi(a)linux.intel.com> Cc: stable(a)vger.kernel.org Fixes: commit 4b147936fa50 ("tracing: Add support for 'synthetic' events") Signed-off-by: Masami Hiramatsu <mhiramat(a)kernel.org> Signed-off-by: Steven Rostedt (VMware) <rostedt(a)goodmis.org> --- kernel/trace/trace_events_hist.c | 30 ++++++++++++++++++++++++------ 1 file changed, 24 insertions(+), 6 deletions(-) diff --git a/kernel/trace/trace_events_hist.c b/kernel/trace/trace_events_hist.c index 85f6b01431c7..6ff83941065a 100644 --- a/kernel/trace/trace_events_hist.c +++ b/kernel/trace/trace_events_hist.c @@ -738,16 +738,30 @@ static void free_synth_field(struct synth_field *field) kfree(field); } -static struct synth_field *parse_synth_field(char *field_type, - char *field_name) +static struct synth_field *parse_synth_field(int argc, char **argv, + int *consumed) { struct synth_field *field; + const char *prefix = NULL; + char *field_type = argv[0], *field_name; int len, ret = 0; char *array; if (field_type[0] == ';') field_type++; + if (!strcmp(field_type, "unsigned")) { + if (argc < 3) + return ERR_PTR(-EINVAL); + prefix = "unsigned "; + field_type = argv[1]; + field_name = argv[2]; + *consumed = 3; + } else { + field_name = argv[1]; + *consumed = 2; + } + len = strlen(field_name); if (field_name[len - 1] == ';') field_name[len - 1] = '\0'; @@ -760,11 +774,15 @@ static struct synth_field *parse_synth_field(char *field_type, array = strchr(field_name, '['); if (array) len += strlen(array); + if (prefix) + len += strlen(prefix); field->type = kzalloc(len, GFP_KERNEL); if (!field->type) { ret = -ENOMEM; goto free; } + if (prefix) + strcat(field->type, prefix); strcat(field->type, field_type); if (array) { strcat(field->type, array); @@ -1009,7 +1027,7 @@ static int create_synth_event(int argc, char **argv) struct synth_field *field, *fields[SYNTH_FIELDS_MAX]; struct synth_event *event = NULL; bool delete_event = false; - int i, n_fields = 0, ret = 0; + int i, consumed = 0, n_fields = 0, ret = 0; char *name; mutex_lock(&synth_event_mutex); @@ -1061,13 +1079,13 @@ static int create_synth_event(int argc, char **argv) goto err; } - field = parse_synth_field(argv[i], argv[i + 1]); + field = parse_synth_field(argc - i, &argv[i], &consumed); if (IS_ERR(field)) { ret = PTR_ERR(field); goto err; } - fields[n_fields] = field; - i++; n_fields++; + fields[n_fields++] = field; + i += consumed - 1; } if (i < argc) { -- 2.19.0
