| -------------- |
| |
| skiboot-5.1.21 was released on Tuesday 19th September 2017. |
| |
| skiboot-5.1.21 is the 22nd stable release of 5.1, it follows skiboot-5.1.20 |
| (which was released 18th August 2017). |
| |
| This release contains one backported bug fix to the 5.1.x series. |
| |
| Changes are: |
| |
| - FSP: Add check to detect FSP Reset/Reload inside fsp_sync_msg() |
| |
| During FSP Reset/Reload we move outstanding MBOX messages from msgq to |
| rr_queue including inflight message (fsp_reset_cmdclass()). But we are not |
| resetting inflight message state. |
| |
| In extreme corner case where we sent message to FSP via fsp_sync_msg() path |
| and FSP Reset/Reload happens before getting respose from FSP, then we will |
| endup waiting in fsp_sync_msg() until everything becomes normal. |
| |
| This patch adds fsp_in_rr() check to fsp_sync_msg() and return error to caller |
| if FSP is in R/R. |
