If another context triggered the DWC3 core's runtime resume, it may have already enabled the Run/Stop. Do not re-run the entire pullup sequence again, as it may issue a core soft reset while Run/Stop is already set.

THIS VERY CONFIDENTIAL

by Greg Hansmann

-- Hello, My name is Greg Hansmann I apologize to have contacted you this way without a direct relationship. There is an opportunity to collaborate with me in the sourcing of some materials needed by our company for production of the different medicines we are researching. I'm aware that this might be totally outside your professional specialization, but it will be a great source for generating extra revenue. I discovered a manufacturer who can supply us at a lower rate than our company's previous purchases. I will give you more specific details when/if I receive feedback from you showing interest. Warm Regards Greg Hansmann Production & Control Manager, Green Field Laboratories Gothic House, Barker Gate, Nottingham, NG1 1JU, United Kingdom.

[PATCH v2 1/2] x86/sgx: Do not fail on incomplete sanitization on premature stop of ksgxd

by Jarkko Sakkinen

Unsanitized pages trigger WARN_ON() unconditionally, which can panic the whole computer, if /proc/sys/kernel/panic_on_warn is set. In sgx_init(), if misc_register() fails or misc_register() succeeds but neither sgx_drv_init() nor sgx_vepc_init() succeeds, then ksgxd will be prematurely stopped. This may leave unsanitized pages, which will result a false warning. Refine __sgx_sanitize_pages() to return: 1. Zero when the sanitization process is complete or ksgxd has been requested to stop. 2. The number of unsanitized pages otherwise. Use the return value as the criteria for triggering output, and tone down the output to pr_err() to prevent the whole system to be taken down if for some reason sanitization process does not complete. Link: https://lore.kernel.org/linux-sgx/20220825051827.246698-1-jarkko@kernel.org… Fixes: 51ab30eb2ad4 ("x86/sgx: Replace section->init_laundry_list with sgx_dirty_page_list") Cc: stable(a)vger.kernel.org # v5.13+ Reported-by: Paul Menzel <pmenzel(a)molgen.mpg.de> Signed-off-by: Jarkko Sakkinen <jarkko(a)kernel.org> --- v8: - Discard changes that are not relevant for the stable fix. This does absolutely minimum to address the bug: https://lore.kernel.org/linux-sgx/a5fa56bdc57d6472a306bd8d795afc674b724538.… v7: - Rewrote commit message. - Do not return -ECANCELED on premature stop. Instead use zero both premature stop and complete sanitization. v6: - Address Reinette's feedback: https://lore.kernel.org/linux-sgx/Yw6%2FiTzSdSw%2FY%2FVO@kernel.org/ v5: - Add the klog dump and sysctl option to the commit message. v4: - Explain expectations for dirty_page_list in the function header, instead of an inline comment. - Improve commit message to explain the conditions better. - Return the number of pages left dirty to ksgxd() and print warning after the 2nd call, if there are any. v3: - Remove WARN_ON(). - Tuned comments and the commit message a bit. v2: - Replaced WARN_ON() with optional pr_info() inside __sgx_sanitize_pages(). - Rewrote the commit message. - Added the fixes tag. --- arch/x86/kernel/cpu/sgx/main.c | 17 +++++++++++------ 1 file changed, 11 insertions(+), 6 deletions(-) diff --git a/arch/x86/kernel/cpu/sgx/main.c b/arch/x86/kernel/cpu/sgx/main.c index 515e2a5f25bb..2ec2d7b7da54 100644 --- a/arch/x86/kernel/cpu/sgx/main.c +++ b/arch/x86/kernel/cpu/sgx/main.c @@ -49,9 +49,13 @@ static LIST_HEAD(sgx_dirty_page_list); * Reset post-kexec EPC pages to the uninitialized state.
